Jonas, Matthew, et al., 

I was able to find this interesting article about clustering in an
"erlangy" way, using synchronized Erlang mnesia databases.

http://tdewolf.blogspot.com/2009/07/clustering-ejabberd-nodes-using-mnesia.html

Does this look like something that could be boiled down into a nice
little script, provided the admin of node #1 made the ejabberd cookie
file and mnesia database available to other FBs?
