The reason is this...if it's possible to use the XMPP provider to connect and chat, it should be possible to use docshare...since docshare is based upon the datashare API, and for the xmpp provider this is implemented using the xmpp message properties (i.e. data that is sent with xmpp messages).  So docshare on xmpp doesn't require a separate simply reuses the existing connection.

I'm not sure it can be purely a server issues, since I'm docsharing quite happily with my co-located colleague. It is just the colleague outside the firewall having problems.

Unfortunately, I'm using an existing Jabber infrastructure, so I don't know what software is being used.

I'll double-check and make sure there aren't 2 jabber servers implicated - is that even possible? - if that is the mechanism used to tunnel through the firewall, it might explain the problem...
