Thanks to everyone for your insightful input regarding wireless embedded
PCs.  You've given me helpful links that were very informative.

Next question:

I notice so far, all the embedded PCs I've looked at have 10/100
interfaces.  Do any come with gigabit interfaces?

Another side note...  What's the largest network you've been able to
support using M0n0wall and embedded PC's?  How robust is this for
enterprise solutions?

Thanks,
Bryen
