The mesh scales to about the same group size that the XO hw will be
able to handle acting as a XS. Right now some usage patterns hit bads
spots wrt mesh routing but we are working on that.

For larger groups, the XO could handle an AP, but that will require
additional hw and complications, but the machine will start hitting
memory and cpu limits anyway. So the sweet spot is small schools -
where mesh will do just fine.

The costs of XO + HD mean that the money savings are there but are not
the main consideration; however, the XO hw is very rugged and low
power. Most of the $500 servers are OTS kit that doesn't deal well
with dust, heat, etc.
