 The @online@ patch that provides @online@ support does not work correctly
 on ejabberd 2.0.1 or 2.0.3 . It will not show presence consistently to
 users.

 When the problem hits, the symptoms are as follows:

 * On the XOs, olpc-netstatus reports that gabble is in use, and the jabber
 server is correct.
 * On the server, ejabberdctl connected-users (or the webbased view of the
 same command) show all the connected XOs correctly
 * On the XOs, the 'network view' screen does not list any XOs, or lists a
 subset of the XOs

 Additional notes:

 * It works transparently when all the accounts are newly created in
 ejabberd.
 * After the first use, XO users will not see eachother when connecting to
 the XS. If a user connects and then reconnects.

 '''Workaround''': When creating the 'Online' group, set the membership to
 '@all@' instead of '@online@'.
