AFAIK the only (hardware) limitation is that a wifi device can only tune 
to one channel (= it can only send/listen on one wifi channel 
concurrently). Everything else are protocol/software limitations. As you 
can see with the newer madwifi atheros driver, it is technically possible 
to have one device emulate several access points concurrently - if the 
driver supports that feature.
