We've just started rolling out our Cisco LRE solution to various places

I doubt that you'll have to worry about the 360 much. Most games do not
take that much bandwidth for online play unless the user is hosting.
You'll find that 20MB of information downloaded in an HOUR is about the
most that any game will use now-a-days (which comes out to not a whole
lot of mb/sec)
So if you have 2 in close proximity on the same channel, then you end up
with half the bandwidth of 2 AP's on different channels. How about when
they are not in close proximity but they overlap as they would in a
standard building situation. How was the performance in the overlap?
