Run a jabber server
From OLPC
OLPC collaboration uses a Jabber server (with a few extra modules and patches) to scale beyond wireless mesh range.
[edit] G1G1
For Give 1 Get 1 users, there is no working Jabber server configured by default, since we cannot handle arbitrary numbers of users on a single server. Look at Community Jabber Servers to see if someone is running a community server you can use.
Then use the Sugar Control Panel to change the jabber server on your XO.
[edit] Running your own server
Currently we only recommend running ejabberd with OLPC-specific patches.
See Installing ejabberd for instructions on installing and configuring it.
For developers, more details on the ejabberd configuration are here: Ejabberd Configuration
If you get a community server up, consider adding it to Community Jabber Servers.
