Brian,
It doesn't have to be a standalone, no. I'll
probably just hook it up to the Linux box and
run MisterHouse! Thanks for the tips on
those products. It looks to me like the only
one that has any real level of Linux support
is the FireCracker, since it has a serial
interface.
X10 Pro, thanks for the links to the
experimental Linux stuff. The reverse
engineering process required to make that
software is tedious and very slow-going,
though, and so far, it looks like the third
party stuff is incomplete as a result. Are
there plans to release specifications for the
device? The same kind of folk who like to
tinker with home automation also like to
tinker with their computers, often with
Linux, and the existence of those pages shows
there's interest. :-)
