Too many people have two layers/features confused into one. Let's please try to stop propagating this confusion. Mesh networking happens at the link layer. If you have an Active Antenna, you are using mesh networking to talk to the server. If you have no access points, the laptops use mesh networking to talk to one another. > Jabber emulates the mesh-functionality so kids can use the sharing > features even though the mesh is effectively turned off when you use a > regular wireless router. Collaboration has nothing to do with the link layer mesh (unless it breaks it...) Collaboration can either happen in an ad-hoc way (laptop to laptop) or in a centralized manner (through an XMPP/Jabber server). Ad-hoc collaboration between large number of laptops generates lots of multicast traffic, which can be rough on a network, and it won't work unless the laptops are on the same subnet. Centralized collaboration works better when you have lots of laptops, and it allows the laptops to be anywhere (not just in the same subnet.) > You set the Jabber server individually on each XO by doing the > following > from the command line: > > sugar-control-panel -s jabber servername You should run the identity manager on your server http://wiki.laptop.org/go/School_Identity_Manager and use "Register" from the Home UI screen. It will automatically set this, and also prepare both the server and the laptop for eventual backup. > Here is the wiki page on EJabber config, it's a bit complex > http://wiki.laptop.org/go/Ejabberd_Configuration That page, while useful, was rewritten by Morgan Collett.
