We have to address theses issues in the new protocol: - what happens when a contact goes offline and online again: does the tube offer remains valid? Other issues? -- Alban _______________________________________________ Telepathy mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/telepathy
