            For the Subsonic 3 I think that the answer is all ready on subsonic site
http://subsonicproject.com/docs/3.0_Multiple_Databases
Also if you look the creation of the template, you see where the connection string is called.
For the subsonic 2, there is a similar way, the connection string can used in most of cases to ask for data.
