I spoke with someone who helped design the t1's, and he said that the t1
100 is -48VDC, and that it "supposedly can be done with car batteries,
but I wouldn't know how".

We recently started looking at some of the new Sun Netra T1's they are fast,
1u high, come in 110AC or 12 (maybe 24 I forget offhand) volts DC. They are
real workhorses and perform great for the size and all. If you configure it
with low memory (sun gets a lot of cash for their memory) they are pretty
cost effective. I know that valinux has some small 2u boxes but don't know
if they have any dc versions.

I don't work for sun. In fact I would like to see a generic version of these
I could run BSD on.

One thing I know to watch for is periodic battery replacement. It
turns out
that running a laptop with a battery in it with AC on all the
time will slowly
erode the life of the battery. I have no way to know how long you
can do this
before the batteries won't do what you were expected. Maybe a battery
replacement every couple years is all it takes.

The other is that the I/O on laptops sucks compared to PCI. For
things that
aren't major traffic handlers (like your DNS and DHCP examples)
this is not a
hit. Do any of the O/Ss out there get full rate out of a 100bT PC card?
