I like the car pc.  nicely fitted in to an iso slot! and the usb on the 
dash is a nice touch.. perfect for copying oggs.  I thought about doing 
one with a wireless card that automatically syncs when in range :)  I'd 
like to know the full tech specs of the system and costs?  I see you 
using ide -> CF which is good but still I think there's going to be heat 
issues?  Is the psu a custom job? does it use power saving to run 24/7 
to avoid long boot delays?  I was going to run a laptop with default 
lilo option set to "incar" mode would have a VERY minimal kernal.  ide + 
sound only. not even VTs or anything and pass it init=my_custom_stuff to 
keep boot up times down, but I think there's scope with a permanently 
installed device to have it powered all the time, maybe even voltage 
monitoring so if the car is left for a long time it will shutdown, but 
for day to day use it's always on... just a thought really.

What are you going to run on it?  I see there's something that looks 
like a camera on the mirror? I'm looking up the ez usb thing now. looks 
interesting, it's not one I'd come across.  I'm very interested in 
getting on with my own engine management system running. but the 
electronics side is a little beyond me, If I could get a base cpu/io 
setup that I could run linux with real time addons on I could program it 
up for the uni project, as just the software would be the project.

On the llu/dsl thing.  llu is local loop ubundling,  if your exchange is 
undundled then easy net will be installing their equipment which allows 
for the 8meg service.  I know I can get it in Kingston and I'm probably 
going to switch.  if you're in a 512k then you'll be with BT's equipment 
which is a 20:1 contention, when f2s resell the 8meg easynet service 
they do it at 50:1 contention.  compare the easynet website prices with 
f2s and you'll see :)

phew, just scrolled up to see the essay I've written. lol.  I'll be off 
before I waste any more bandwidth.
