I don't have any idea myself, but I'm curious as to the nature of the actual data collected as well. It would be rather desirable to build a replacement for the preloaded JoikuSpot - besides the possible spying, the lack of 5 GHz support, limited choice of channels, and lack of infrastructure mode are also huge issues.

The problem however, last I checked, was that infrastructure mode isn't possible without a new wireless driver, which itself can't be replaced without modifying the kernel, which requires going into open mode. However, I'm not 100% sure that kernel modifications are actually necessary.
