You should use the "distributed D-Bus" mode of Telepathy Tubes; this will allow it to work in any environment where chat works, in a transparent way. My colleague Morgan Collett (morgs on <a href="http://irc.freenode.net"> irc.freenode.net</a> #sugar) is working on a Tubes "hello world" example which you'll be able to use as a reference, and on improved client-side API so Tubes are easier to use. We plan to make integrity transparent - communication with the server is currently cleartext but will be SSL/TLS later, while communication across the mesh network is currently cleartext but will later be authenticated and possibly signed. The signing will be done with the "owner key" (a DSA keypair) which is generated when you first use a new OLPC. If you want to provide integrity guarantees before we officially support this, you could generate your own signatures at the application level and send them along with your messages - binary blobs (in the form of byte arrays, signature 'ay') are fully supported by D-Bus, and hence by Tubes.
