It may be trivial to impersonate traffic, but if it doesn't make sense in 
the context of the current communication, it will be rejected.

WPA2 (now 802.11i) provides protection against replay attacks by changing 
its IV periodically. It also uses 128-bit AES encryption. I am confident 
that it will be the standard promulgated by Cisco now that it has been 
ratified. If you need to know more, Google '802.11i replay attack'.

WPA now, that is a different kettle of fish!
