James: This does seem like a radio issue, though it might not be vendor neutral. The likely cause of the problem is that the front end of the receive radio of one AP gets overloaded by the transmit of another AP. Even if they are set to different channels, the RF stuff is all the same so that they can be set in software. If a vendor has better filters, they may be able to place APs closer together. Also, if a vendor has APs intended to be used that way - so that they synchronize when they transmit to avoid transmitting directly into each other, that would allow closer installations.
