Dan,

to come back to this. You want something a bit like this:

class DatabaseConnection(Persistent):
	implements(IDatabaseConnection)

registered locally and called as a named utility

db = getUtility(IDatabaseConnection, u"the specific connection")()
db.execute("INSERT (gromit, doodah, wotsit) INTO thingy (?, ?, ?)",  
(*args))
