Sounds reasonable; i wasnt sure if this is how it is done.
Enlighten me: can a $5 802.11 card with a single radio form multiple
associations and keep them at the same time? A while back i read an
interesting paper about someone doing VOIP on linux using such a
technique (I can look it up and send you a reference; i think it was
either out of berkley or stanford).

yes, this would work. However, i am still interested in the case where 
you have a single radio but multiple AP connections - unless this is 
impossible. I have to go back and look at that paper - I know they were
using very basic 802.11
