Thank you for the reply.
I've noticed in a thread from May '08 the following
Our situation is similar: we must package and deploy user databases along with supporting scheduled jobs to client sites that are locked down and firewalled. So, we are looking for a solution that can enable a client to use a simple executable by which they can create a user database schema, a few lookup tables, database logins, and a small number of enabled scheduled jobs.
It sounds like from the post I've quoted above that this might be possible in SQL Packager, if it's approached cleverly through the API ...?
