My system has a number of ManyToMany cross database joins. We do not seem to have any problems with them. We do not Collapse them. We maintain them manually.

Dear List,
I've got a design question: Is it possible to manage cross database ManyToMany relationships with EOF?
Googling the topic brought up:
http://lists.apple.com/archives/webobjects-dev/2003/Feb/msg00395.html
which gives me the faint hope that such things are possible. But then again almost all of the other search results gave me the impression that this isn't possible.
Hence my question to the pros: Are such constructs possible, if so what do I have to pay attention to (Of course I tried and failed before asking this question ;-))? What are the pitfalls?
If this is not possible I'd like to know what kind of solutions you use in such situations: duplicate tables (which bear the risk of divergence)?
thanks & cheers,
Lars
