Re: TC wifi initializtion - concept

Anything that uses the SDL toolkit for graphics is barely usable at 100Mbps
and less than 1GHz on the client cpu. Tuxmath is barely usable with a 1Gbps
network and a 1.5GHz client cpu.

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
