Hi Ashley,
Cayenne architecture should provide for clean support of nested and
distributed DataContexts, though it doesn't support them at the moment.
There are definite plans to include both in Cayenne. In fact this has
been asked so often lately, that I think it is inevitable :-)
Any help or volunteering to take a lead is definitely appreciated.
