[Sugar-devel] Default Collaboration Server

[Tony Anderson]

Currently, ejabberd is used on the school server (with gabble). Does 
this change mean that something must be done on the XO or schoolserver 
to enable collaboration (it is now automatic)? So far as I know, the XO 
uses salut for ad hoc links and gabble with ejabberd. Generally, if it 
isn't broken, don't fix it.
