of course, the problem is that there are no "non-overlapping channels" 
in 2.4GHz.

And please don't cite that tired old "1, 6, 11" transmit mask argument 
unless you're
ready to talk about the selectivity of the receivers.

Short answer:  no, it doesn't work unless you're prepared to add a lot 
more cost/engineering.
