A 486/55 w/ 1gb disk and 32Mb of RAM is plenty of hardware. I
have no idea what one costs since the price of such hardware drops
every day. :) BSDI is about $500 on top of that. Not a lot of
money, all things considered. Such a machine can handle a T1 line
without much trouble -- after all, a T1 is a pretty low data rate
and a 486 is a pretty zippy processor.

It's very likely that the reference platform for the toolkit with
switch to BSDI [from SunOs] very soon. "porting" it, in either case, is
a matter of changing a line in one Makefile, and another line in
BSDI is also very attractive, now that screend has been released
for it! It can now act as a semi-permeable dual-homed gateway.
