OK, but perhaps normal laptops are not accurate enough analogues to a bunch of XOs. Has there been much measurement of simulated or actual XO app traffic to see just how much yak is actually going on? > We're likely to have that many laptops in a single classroom, and > when you get a couple classrooms next each other... But don't you get a factor of only 3 more with the multi-channel scheme? Any schools with more than three adjacent classrooms (coarsely speaking)? Could the system switch between the multi- vs. shared-channel schemes considering its perceived traffic intensity? For away-from-schoolhouse stuff (which would probably also mean away-from-internet), let the system use a fixed channel (or, say, wherever it detects most nearby XO's are already squatting). Let it try to move elsewhere only if the local traffic is too loud. - FChE _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
