I'm looking for similar suggestions, but with more emphasis on
getting the first copy running quickly and cheaply. Since I'm
counting engineering time as a cost, I'd happily pay $200 more
for hardware if it saves a week of engineering. Accordingly, I'm
hoping to find a single-board computer that boots Linux from
some kind of flash filesystem, plugs into my house ethernet,
has a handful of analog inputs and digital outputs, and runs
ssh and some kind of web server.

Likely candidates appear to be

 http://www.applieddata.net/products_bitsyX.asp
I have the feeling Gumstix is likely to have something, too,
but when I try to use their web page, I always end up going
in circles: http://www.gumstix.com.

If anybody is familiar with these systems, or others that
may be better suited, I'd appreciate hearing about it.
