You'll probably have the most difficulty with megrok.rdb.

z3c.saconfig however exposes a function 'named_scoped_session'. You can 
supply it with a name to get a session object that works with a 
particular database setup. If you register the session utilities with 
names this should work. (I think the same applies to the engine stuff)
