@greg@identi.ca why not just something like a PI2 and keyed ssh accounts. I run such with currently 3 people using it and me doing most of the admin. But may farm some out to person 3 soon. (Its actually an old netbook with some newer bits on the PI2.) Hoping to move to a fully PI/beaglebone system down the road. I run many services mumble,xmpp,email,web, etc.
