    My thoughts exactly. For how much I use it, a new smartphone is a steal at $200

    That supposes that (i) you want to have a data plan and (ii) you like any of the phones they have.

    I know a number of people that don't like any of the phones so they haven't upgraded in a while either.

    And now that AT&T requires a data plan for any phone with a QUERTY keyboard or touch screen - e.g. pretty much all their phones - your rate may go up if you get a new phone and didn't have a data plan before.

    Now, while you may think the $200 is cheap for the smart phone consider the changes in pricing as well. For me, I don't have a data plan. So to get a smart phone also means getting a data plan. If I got an iPhone that would be a data plan for 2 years. So $200 for the iPhone + $30*24 ($720) totaling $920 vs. $800 for the iPhone outright and no contract modifications. Though suppose you get a $200 phone with the minimum data plan - $5/month - $200 + $5*24 ($120) totaling $320 - did you really save much?

    Oh, and if you have multiple phones on your account (e.g. a family plan) they all have to have separate data plans - so that is $30 per phone. A family of 4 each with an iPhone and you're paying $120/month just for the data plans without even talking about anything else.

    Lesson: do the research first. It may be cheaper to buy a phone outside of AT&T or T-mobile paying full price for it than to get it through AT&T or T-mobile. Of course, any other U.S. Carrier screws you over since you can't change the phone without them knowing since there is not SIM card to just switch around.

    IPsec is only useful for securing communications between two specific nodes for a specific communication channel. It does nothing for securing a network.

    On the contrary, IPsec defines a protocol for securing connections between a security gateway and a host (network-to-host mode), in addition to the host-to-host and network-to-network modes. Using this protocol on a router you could securely authenticate client devices and limit routing to authenticated incoming packets.

    But first you have to know about and be about to get a route to the router. That requires a valid IP address on the network and information about the network.

    ... separate software then monitors the network for MACs and addresses not on the official list, alerting appropriately.

    Exactly—separate software, not DHCP. It's not much of a security feature if your DHCP server just accepts requests from any device which happens to ask, and if you have a way of actually authenticating clients you might as well use that by itself and skip the DHCP.

    Except you can configure DHCP to only provide addresses to a known set of MAC addresses. It doesn't have to give one out to anything on the network; it could even require authentication via Radius or other mechanisms first as well.

    Also truly secure networks only use static addressing and monitor for any unauthorized addresses, etc. on the network. This doesn't work for IPv6 since IPv6 by default assigns an address even without a DHCP server - something that is not desirable in all situations.

    IPv4 will also assign addresses without a DHCP server, in the link-local 169.254.0.0/16 block.

    No, that's just Microsoft. No other sane IPv4 stack that I know of (and I'm not calling Microsoft's IPv4 stack sane) assigns in that range. Also, even when Microsoft's does - you cannot go anywhere on most networks.

    Unix/Linux/Mac/etc if no DHCP server is available just fail and do not enable the interface at all. No IP address is assigned.

    IPv6 only assigns global addresses automatically if you enable router advertisement; they can also be assigned statically, directly on the client or with DHCPv6 (which is supported natively for Windows Vista, Windows 7, and Windows Server 2008 clients, not to mention Linux; free third-party software is also available for clients, servers, and relays).

    Linux supports yes; but find a working DHCPv6 implementation please - and one that is available on most distributions.

    Windows - I can believe Win7/Win2k8; but not Vista - unless they changed it in an "update". I have managed an IPv6 Windows network before; and no DHCP is not even possible. Windows does not even offer the possibility in the configuration; nor is static IPv6 assignment.

    And as I said - please point out these clients/servers/relays. I have looked. DHCPv6 was shutdown because ISC's DHCP 4.1 and later has DHCP IPv6 support - but it's not available in most distributions yet; even Ubuntu and Gentoo are stuck on ISC DHCP 3.x.

    IPsec

    IPsec is only useful for securing communications between two specific nodes for a specific communication channel. It does nothing for securing a network. It works for VPN as VPNs around all data between the diverse networks over a single communication channel (or multiple channels bonded into a essentially single channel). That is not the security I am talking about here.

    DHCP does nothing for your network security. It's a voluntary protocol. Anyone who wishes to join the network can simply choose any available address and configure their interface to use it statically. They will then be invisible to your DHCP-based "tracking" system.

    Only works for valid addresses on the network; and then you must get every little detail right for that specific network. That's WHY we have have DHCP - to assign valid addresses and inform of the network configuration. Now granted, they designed that into IPv6 as (i) the auto address assignment (MAC+LocalLink) which provides administrators no method of controlling the address ranges, and (ii) Neighorhood Discovery which tells everyone about everything automatically - again, administrators have little to no control other than to try to track down the offending user and physically remove them. On the other hand, with DHCP you can control the configuration. Granted, some may stealth their way in and figure out the configuration but the majority will not. With DHCP you can also setup methods to track the MAC and then alert for unauthorized nodes - e.g. DHCP registers a MAC+address, and separate software then monitors the network for MACs and addresses not on the official list, alerting appropriately. Take away the ability to control a network via DHCP and such tools go away. Also truly secure networks only use static addressing and monitor for any unauthorized addresses, etc. on the network. This doesn't work for IPv6 since IPv6 by default assigns an address even without a DHCP server - something that is not desirable in all situations.

Additionally, only AT&T and T-Mobile use Sim cards in their phones (you can get international phones for Verizon, etc. with SIM cards to use when you travel internationally, but they do you no good at home), thus locking people in further. Add to it that the carriers are the prime sellers for phones and it's not a nice market.

    Honestly, the carriers should be forbidden from (1) selling phones period, (2) forced to focus on the network and services they provide, and (3) from doing the contracts; that's the only way the market will become more fluid.

    DHCP does not necessarily work with IPv6. Microsoft's IPv6 (Teredo) platform doesn't support for example, at least Win2k+IPv6, XP+IPv6, Vista, and W2k3 (I don't know about Win2k8 or Win7, but they probably are using the same IPv6 stack).

    That said, DHCP for IPv6 is in a sorry state for pretty much all platforms as most are ignoring it entirely. ISC DHCP Server 4.1 and later supports it; but few distros if any support it. Even Gentoo and Ubuntu only provide 3.x releases as 'stable' releases.

    And for those that think DHCP is not necessary - it has many benefits. From configuring the network (yeah, yeah, Neighbor Discovery provides that) to some network security - can't operate on the network without a valid address. Personally, I don't want anyone on my network that I have not authorized to be on it, and when they do get on I want to track them accordingly. DHCP provides a great benefit in that - since I know their MAC address and their network address; and if I expect they'll be on more often, then they'll get assigned their own static and DNS as well.

    Until those kinds of things can be supported IPv6 won't go much of anywhere no matter how much IPv6 acolytes want to switch the world over.

    Q: What difference will The Document Foundation make to developers?

    A: The Document Foundation sets out deliberately to be as developer friendly as possible. We do not demand that contributors share their copyright with us. People will gain status in our community based on peer evaluation of their contributions - not by who their employer is.

    So I'm guessing that was a Sun or Oracle requirement, probably Sun since they also had Star Office under a Commercial License so they probably wanted the copyright assignment so they could do Star Office, where as the Document Foundation seems to be set up so as not to have any kind of commercial offering, more like Mozilla; also from the FAQ (emphasis mine):
