 Hi!

 It turned out that the direct file transfer is not the only problem here.
 I was able to negotiate a direct connection between the two parties and
 the file data is sent through it just fine. However if there's an
 estabilished direct connection between two parties then the official
 clients send other invitations (emoticon, user display picture for
 example) on this channel as well to lighten the load of MSN servers I
 suppose. This doesn't mean that the transferred file will be corrupted
 because these messages can easily be spearated from the file data. But...
 they can't directly be fed back to the existing handlers because of the
 slighty different format and the response generated by handlers will be
 sent through the MSN servers by default rather than the direct connection.
 So the direct connection has to be integrated into the slplink and its
 corresponding slpcalls. I've come to this conclusion a bit late and
 realized that some of my code is redundant because with the appropriate
 modification the existing slplink/slpcall routines will be able to deal
 with direct connections as well.

 Okay that's enough talk... I've attached the patch which enables some
 '''limited direct file transfer'''. The caveats are:

  * You'll be able to receive/send one file at a time '''with a specific
 party'''.
  * Invite messages (emoticon, user display picture for example) won't be
 received during the file transfer.

 If I find some time I'll work on the proper direct file transfer so don't
 panic.

 Cheers,
  Kukkerman
