    Just to clarify my situation, I am not actually co-locating the APs,
    just spreading more and more around our building. I need to keep 
    coverage of the whole building. Clearly, I am not using gain antenna,
    they are all standard omni's.
    It's a bit like the four-colour map-colouring problem

Yes, it feels exactly like that.
No doubt the digital mobile 'phone people (Do they use DSSS or FHSS?)
encountered it early on and devised interesting solutions.

    I'm going to try reducing the channel spacing to use channels 1, 5, 9 and 13.
    I should get 18MHz of clear radio bandwidth between these channels, hopefully
    enough to keep it all working at 11Mbps per AP simultaneously.

And please let us know how you fare.
