This sounds more like the direction I should go.  Is XML-RPC the only
technology allowing this sort of setup?  If I understand correctly, it
would basically mean going to a three tiered application approach.
I'd have the database, the python xml-rpc server, and the gui/web
interfaces.  I'd also want to make sure I'm implementing technology
that will scale well.
