Mitigating interference from other 2.4GHz operations is one of our major preoccupations at C-U Wireless. I keep trying to think of ways to do it cheaply and automatically. Somebody suggested to me that to add a null to our omni antennas, we can suspend a thin metal reflector somewhere in the near field. I wonder if one could use a Nitinol actuator wire to simply and economically move the reflector, thus rotating a null over an interference source under computer control? The devil's in the details, but maybe you can build a poor man's adaptive antenna for the price of some Nitinol wire and a bagful of components from Radio Shack and the hardware store. Then again, $5 smart antenna chips may come to market before anybody does tricks with Nitinol.
