Yeah, I didn't mean to imply equal divisions either (50/50 was just an example). And the underlying issue I'm trying to get at is in the data model rather than the UI. There is new information needed about a resource (in this example, whether (s)he is 100% available overall in all projects or only 50% available overall) which is not captured in either project #1 or #2 (in which the resource is 50% available in both).

So in order to support what we're talking about here we'd need some kind of additional store of information about resources that is outside of and in addition to the projects themselves.
