This is the first time I've seen UWB described as impossibly cheap. The timing required to pick out the signals requires some sort of fancy chip capable of nano or pico second resolution. Maybe they solved that recently but I've never seen it described as capable of being done with "commercial grade" chips.
We've been reading about UWB for years and the FCC won't approve it. So my guess is we won't see it soon.
I slept through E&M so I can't speak from knowledge but the 100 MPG Carburetor is a good analogy. The supporters say it does everything including make julienne french fries and that other engineers just don't understand it. The other engineers say it's just a pipe dream and I've never really seen anything I would consider unbiased analysis for either side.
Yeah, you heard that right. ISP's can assign static addresses via PPPoE. I'll admit that it isn't as easy as with DHCP assigned addresses but it can be done. BellSouth.net is already doing it for business customers and plans on doing for residential. I've also seen posts claiming PPPoE was a hack. Considering DHCP was designed to be used over a LAN using it for DSL in a bridged Ethernet over WAN mode makes PPPoE look like a MIL spec design. The fact is PPPoE scales better for the ISP. It makes it easier for them on several levels actually. I know it's fun and easy to bash ISP's and even more fun to bash telco's but sometimes what's good for them is actually good for us too. It creates some short term problems for people that have adapted to the crap that is DHCP over DSL. I would have preferred DHCP since it's easy to setup. I got a choice between PPPoE and PPPoA. I dumped the crappy Speedtouch USB modem, bought an old Alcatel 1000 off ebay, bought a netgear cable/dsl router because I needed IPSEC tunneling and I've been happy ever since. Adapt!

I think the biggest problem is politics.
