Last I heard aol can do a server push, download files from and delete files
from the clients harddrive. This implies a mini-server is built into the
client. If that
is not secured then it is at least vunerable to spoofing attacks.
Any comprimise in the dns tree or ip routing between you and aol
and a trojan aol service could do anything the real aol server could to your
 machine. 
This is based on old memories but it caused quite a stir when some users
found out
aol could reconfig the users local software. But I am not the expert.
Perhaps someone at aol will correct or enlighten us. If the "mini-server"
can be 
block or disabled then I would like to know it. (So would most of the people
allowing this stuff thru their firewalls, I hope.)
