...limiting "ourselves" - there is a certain infrastructure on that product involving several resources.

I faced that situation at several times during the last 10 years in consulting. At first, it was difficult to understand. Then, I got use to it. Then, for other related reasons, we also decided to apply it on the latest product which is about to be released (or should have been released if it wouldn't have been because of the VFP OleDb provider failing on high traffic).
