The BeagleBoard www site says they will be at MakerFaire this weekend.
It certainly is a good chance to discuss some sort of group discount for
us, even if they don't sell them directly.
What if we structure some sort of 3 hour long workshop?
We could provide the useful documentation to enable the preliminary
work. For FreeBSD, there's stuff out there. People should prep their
SD cards at least.
A short introduction to get people started would probably be nice.

You know, I've been interested in this, but one thing I'm not clear
on (and what's most interesting to me) is what the differences
between all these units are as far as interfacing with the outside
world. Specifically, if I want to control a small servo or
similar, or tie into a bank of small relays or some such thing,
what are the options? Does that mean buying yet another device or
is there some basic analog I/O on these things?

If you have a Raspberry Pi you should take a look at the Gertboard
which is an expansion<br>
board that you can use to easily interface with servos or sensors
via gpio.<br>
