For AIM communications, we can use AOL's proxy server for file  
transfers and direct IMs.  It should work (in theory) with the  
existing clients.  I would not be surprised at all if they are not  
already using it.  If a client makes a connections to  
ars.oscal.aol.com, then it is a proxied communication.
