Fast Gaim stödjer (om än buggigt) filöverföring med AIM och AIM och ICQ är samma protokoll...
http://trac.adiumx.com/wiki/FileTransfer:
Which protocols support file transfer?
(Taken from the Gaim FAQ - This information applies to Adium as well)
Does Gaim support file transfer?
Somewhat, yeah. As of 1.2.1 the following is supported:
• Sending and receiving files on AIM (although it might be a bit buggy)
• Sending and receiving files on Jabber
• Sending and receiving files on MSN
• Sending and receiving files on Yahoo (sending is limited to approximately 1 megabyte file size)
Most of the protocols themselves support file transfer, but Gaim has not been written to support it yet. If you would like file transfer to work better or be more complete, get CVS and submit a patch using the generic file transfer API.

Improving AIM file transfer
Users behind a router may have better luck with AIM file transfer after forwarding ports 5190 - 5200 to their machine. AIM file transfer and Direct Connect are interrelated.
Why does AIM file transfer work in iChat and not in Adium in certain situations?
Official AIM clients such as iChat have access to an AOL proxy server that acts as a middleman negotiator for the file transfer. libgaim does not support using this proxy server yet, so such situations can't fall back on using it.
Och när vi ändå håller på, här är varför MSN-överföringen är så långsam:
Why is MSN file transfer so slow?
MSN file transfers in the protocol supported by libgaim go through the Microsoft server. They are therefore very reliable but also quite slow. MSN7 and other MSN clients support a direct person-to-person transfer as is used in AIM... this is not yet supported.
