Sugar collaboration is built on top of [[wikipedia:Jabber|XMPP (Jabber)]], an open and extensible [[wikipedia:instant messaging|instant messaging]] protocol. Collaboration via a server is more scalable than over link local connections. This server is a Jabber server (with a few extra modules and patches) and is usually included in the XS schoolserver for school deployments.
Community members such as G1G1 XO users, and developers, can use a Jabber server for collaboration without needing the rest of the schoolserver functionality. In this way, "mesh view" can be extended over the Internet for regional or global communities.
