Problem I have with (2) is more from the point of view of a public 
It will not allow the user to 'attach' a file to the conference - so 
that people joining the conference 'later on' also have a way to 
retrieve the file.
Ofcourse , one way to look at it is , if you were not online when I 
tried sending you a file - you dont get it : like in normal case :-)
Yes , it would be great if we can chat more about this - it will be 
useful to come up with some guidelines such that any client can leverage 
this - not just mine with my server or yours with your server :-)

Torrents would help us negotiate NAT's too ... interesting alternative
