I don't think you'd want to network-boot over wifi, but has anyone
tried more than a few sessions of NX/freenx or x2go over wifi
simultaneously?   I use it myself from a laptop frequently and think
it is great for everything short of streaming video but don't know how
well it scales.   If you aren't familiar with the NX or x2go
technology, it adds proxy/caching/compression on both the server and
client sides to greatly reduce latency and the overall bandwidth
needed, and it has cross platform clients.  Otherwise it appears as a
normal X desktop, adding the option to disconnect from running
sessions and reconnecting later with everything still running (even
from a different client).
