I hacked up a patch to do this a while ago, and I've since mentioned
it several times on this list. You can find it at:

http://www.mattb.net.nz/blog/2006/10/09/per-client-vlans-with-madwifi/

I've pretty much abandoned it now, the shift to the in kernel 80211
stack gives much the same functionality and has much more chance of
being maintained in the future. You're welcome to whatever you can get
from my work though.

Cheers
