So this would mean there would be a central point of failure in my
network and wont be able to have a system where any node can come and
join/leave the network without affecting the complete network.
I would give 7.X a try with madwifi trunk and see how far I can go. I
probably don't need multiple per-device group keys and such as every
node in my network would have the same keys. I probably need supplicant
mainly to initiate/maintain the crypto for my wifi traffic then anything
else.
