AIM & VPN

[acidlust () TAMPABAY RR COM (jeff D)]

Marc stated that there is weak encryption in the VPN that  AIM(aol instant messenger, standalone from AOL)  utilizes 
when in a direct connection.. What i would like to know if there is how this vpn is created and how it can be created 
if VPN services are not installed.  Does AIM use it's own version of a VPN service? .  IF anybody knows of somewhere 
that i can find out more about the AOL protocol in not extremely complicated terms. thanks.  I've searched and all i've 
found is how to implement it in linux.. i guess i'm not searching hard enuff.

thx
