Cool, thanks Ian. I am trying to build my models based on functionality around the DBIC ethos, not quite as a direct model->table mapping as DBIC creates, but for example all functions that require access to the 'Users' table, will have a 'Users' model and all functionality regarding logins, logouts, user name and other stuff kept in that model.
Separating it all into the correct models with all the desired methods isn't easy and will take time to formulate, but even though I'm not using Catalysts ORM/CRUD, I am still trying to stick to an MVC paradigm! I have a long way to go for sure!

Yes, try to keep it out of the Controller. My opinion is, that if you have business logic that uses data from two SQL servers (each of which has it's own model) then this would be a model in it's own right. First think of this business logic outside of Catalyst, it might have accessors for each of the SQL instance objects. Create a BusinessModel for this logic. You might find that this then becomes the only Model that you need to access from Catalyst, and the SQL server objects are not directly called from Catalyst, but are subsumed by BusinessModel. Then use Catalyst::Model::Adaptor with your BusinessModel giving Catalyst access to all of it's methods.
