OK. I found the Reference Manual for FW/1, and I'll give that a read through.
I think I get what you mean by DI (specifically DI/1 'framework' calling itself a framework).
My framework current DOES build the inital objects off of an XML file (auto-wiring objects into others, like the aforementioned User Gateway Object into the User Service's Gateway property.) I think if I give both FW/1 and DI/1 a read up on their manuals (and hope that they are written well to explain their process), this will help to give me insight about simplifying this inter-object dependency and what may be the most optimal way of referencing that.
I do like how Sean simplified (convention) the MVC process.
