Yes, and that's the direction in which I want to take the XS.

Agreed -- I want to keep XS as simple as possible.

and XS-AU was done in a very useful way; Jerry's work is in many
senses stuff that I intend to follow with the XS going forward.

That's an interesting concept. I hadn't thought of that. If this
classroom-XS runs its own network, and nothing else, you'll need
hostap, or an AP. If it's going to be part of a wider network
(school-wide, perhaps w Internet access) it needs 2 NICs. Ah, I see
you've thought of that.

Note that running hostap is not a trivial endeavour.
