I think the main issue with the whole file transfer is that the aim is
to keep the file transfer out of the xml stream used by the jabber
client itself .. xml isn't good at binary, and large quantities of data
make IM become NQIM .. Not Quite Instant Messaging :)

One of the key problems of the client serving the file is that it stops
anyone behind a firewall being able to send files, something that will
affect many business users, and often normal home users too .. I know of
several isps who put give dialin users a reserved class ip address, and
use a masquerading firewall for the net access .. its secure, and
protects the users, but it also stops anyone being able to see your

I used HTTP as a reference as it is the most popular of the protocols
mentioned, and many people already use that for the various different
mini-implementations i've seen .. there is nothing to stop you from
using FTP instead of HTTP, apart from the fact that HTTP is still
prefered in the whole scheme of firewalls than FTP is from what i've
seen .. although I may be wrong and i'd be the first to admit that :)
