The answer, at least for cable, is that the existing infrastructure doesn't allow the high-speed access in most of the cases, and need to be upgraded. This takes lots of time and money.
In case of DSL the situation probably the same even if DSL camp claims that the 'existing infrastructure can be used'. There is also a number of distance limitations.
I for once agree with Eric Raymond. Both Marxism/communism and nazism are fundamentally the same. Their core belief is totalitarian society. I have a right to say so. I've spent 27 years of my life living in such a society. As to 'american rednecks', let me point out that disproportionally large number of american academia still worship Marxism and communism. Those people should truly be called american REDnecks. Quite paradoxal situation, I would say. The products of 'academic freedom' advocate the system which fundamental unfree, and furthermore ostracized everyone not agreed with them.
In the environment where you cannot change your MAC address (like a cable modem), mostly likely you can't change your IP address as well. In the environment you can fiddle with your IP address, you can replace your hardwired MAC address with 'soft' arbitrary MAC address. This MAC address must be unique within your broadcast domain, but that's about it.
The whole issue is nothing but lots of fluff. Bill Frezza has no clue. I don't really care about IPv6 in general, but - hell, this particular issue is not the issue at all.
If I send something in open, I use my IP address anyway. It is in DNS. It is mapped to my machine, with my name as a part of the machine. However when I have to hide, I'll go to extra efforts to hide my origin. Well, so I'll replace my hardwired MAC address with something else. Big deal.
If you are old enough to remember the Desert Shield, Patriot missiles should ring the bell. If not, let me remind you. There was much ado about those missiles, and how they destroy the Iraque's Scuds. After the war, however, we've finally were able to read the true story: there was not a single instance where Patrior missile actually homed on Scud and killed it. It was mostly a propaganda, pure and simple.
There were several instances of fake or 'well controlled' tests with other anti-missile missiles.
I am for strong defense, and that's why I'm concerned with sometime too cozy relationships between the military and companies like Ratheon et al. This is what is called a 'military-industrial complex'. Lots of moneys are getting wasted, thanks to this complex. I hope this won't undermined our defense capabilities too much. Oh well...

Why every toaster on the internet needs to be connected?
Well, how about my toaster talking to your toaster? ("Oh boy, I"m toasted" - 'Me too').
I agree that private addresses and NAT serve quite well to aleviate the address shortage. What people don't understand BTW is the complexity of move from IPv4 to IPv6. I work for fairly large first-tier ISP, so I have some rough idea what would it take. MOre than considerable effort. In any case it seems like V. Cerf is the only one who promotes it. Otherwise nothing short of a complete meltodown would force the move to ipv6.
You now, the whole tenure business is to insure the academic integrity (or I think so).
The whole story reminds the my friend's cat who's name was Leibniz (the german phylosopher and mathematician, if you remember your calculus I). Leiby has a habit of rolling on this back and having anyone scratching his belly. THis reminds me those 'independent academicians and researches' on Billy's payroll. They are only happy when someone scratches their bellies... (but I digress)
what I've heard on NPR is these guidelines are rather biased. Apparently in terms of Y2K, Italy is as just unprepared as Ukraine, but since italy is US' ally (for god sake), the guidlines say something like 'Italy could have done more work', whereas Ukraine is simply rated as 'unsafe'.

The rate-limiting feature of cisco routers currently allow to 'slow down' the sessions with specific source or destination. there is no magic in it, nor it is a 'hidden feature'. it can be used for various purposes. in fact it works really well (I've spent the last few days playing with it). I'm sure other routers' vendors have similar features.
Performing it straight on an interface shouldn't hurt too much - although I gotta admit, I've got no numbers to back me up here.
- Yes, the overhead is something like 0.001% or less. Can live with it.
Matching per IP address is rather CPU intensive though, according to the documentation.
Actually, it's a bit more involved than that. According to documentation, using the standard access list (if you wish to match IP addr) shouldn't be that bad, but using the extended access list (if you wish to match say TCP port number) causes more overhead. What we've got is something like 10% overhead with a standard access list, and >20% with extended access list.
By overhead I mean 'the packet rate which still can be processed by CPU'. (on input for instance, you'll see 'ignores' if CPU can't keep up with the incoming packet rate)
You know what really bugs me all the time. I am using Perl a lot, and yet those folks... Gosh, don't you think they have made a religion out of it? Just look at the Tom Christiansen web site.
PERL is a language of post-modernistic epoch.
PERL is a spirit of UNIX.
and so forth and so forth.
THose folks surely do have super-inflated egos. In fact, PERL is quickly becoming a kitchen sink, rather incoherent collection of features noone really understands, just take a look at the discussion on PERL usenet groups. These are no longer the rational discussions, but rather sort of 'how many angels can fit on a tip of the needle'.
Saying so, I am still using PERL for quick and dirty work, but when I fell I need to have a high degree of confidence in what's going on, I am using C, compiled with GCC.
As far as Tom's article is concerned, remember boys and girls: MEAN PEOPLE SUCK.
THis is not the cost of IPv6-capable router (well, practically all the routers used on INTERNET backbone are IPv6 capable) but the *cost of converting the INTERNET backbone* which is the major stumbling block.
There is very little motivation amongst the major ISPs to migrate to IPv6. The main reason for IPv6 - the potential address shortage - has been blown out of proportions. More efficient address space allocation, as well as extensive use of private addresses and NAT make 'the day when we all run out of address' further and further off. There are no other solid reasons to move to IPv6. The only other reason I can think of - very elegant scheme of assigning addresses to the host - is no longer relevant due to the wide speard of DHCP.
Granted, the large address space is indead much better than the combination of private address and NAT, as well as the IPV6 scenario for allocating addresses to the host is better than DHCP - but not at the extent to justify the massive conversion of INTERNET backbone to V6.
What I've heard from someone who's been participating in IPv6 committee (can't give his name but there is a hint: he wrote several key RFCs 'on how to write RFCs' and also teaches at Harvard) that the whole IPv6 was nothing but the big P.R.: IP was still evolving, its enemies has been trying to speard the FUD, and 'runing out of addresses' scare was part of that FUD. Consequently, IPv6 specs was mostly response to that FUD. Of course now IETF feels kind of funny: they've spent so much time and efforts and seems like noone cares.
AFAIK, Metcalfe is indead doesn't know what he's talking about. He *is* completely out of touch.

As far a 'cocky little punks'... well, I've been in computing/networking business for about 15 years, currently work for one of the top-tier INTERNET providers... We make INTERNET work, buddy. What are *your* credentials, by the way?
Robert Metcalf has invented Ethernet, and that has truly revolutionized the whole networking business. Since then however he didn't make a single contribution to anything AFAIK. He became a columnist and every once in a while fires the cheap shots just to attract attention to himself (so I guess people can still remember him)
Last year Metcalf predicted the INTERNET would come to the gridlock 'during the last year' or so. It didn't happen, and he had to eat a crow. Now he's doing it again.
Seems like he doesn't understand the nature of INTERNET, and apparently he doesn't understand the nature of the open source movement either.
they say 'it is possible because digital signal takes less bandwidth than the anolog'. This is BS. Digital signal takes *more* bandwidth the analog. Substantially more. But then we can do some fancy things like MPEG-2 compression, and that's how we can keep the bandwidth requirements for digital video within the reasonable bounds.
