Ok here is the problem. All direct file sharing programs or online collaborative programs puke when both users are behind a firewall, or quite possibly a NAT. This mean that Lauren, who is behind WMU’s firewall cannot send files to me, behind CURF’s firewall or vice versa. This also means that I cannot use the whiteboard to help her with homework or send her pictures in Instant Messenger. I have tp upload anything here then she downloads them from here.
I think the next project may be the creation of a collaborative whiteboard system, probably designed with math in mind. This whiteboard would run on the web server and could be used by more than one person. Two is the requisite.
If anybody knows of such a system, which works regardless of firewall settings, please let me know! post a message in the forum or email me. Otherwise I will start looking into writing one myself.
