I was wondering if JUnit would want a small 4 class library that creates mock objects or allows rapid development of mock objects.  This library includes 4 sets of examples and 3 sets of test cases.  For a little library I think it is extremely powerful and flexible(well, my opinion at least as we have been using it for over a year now).  If you would take this under consideration, I would be happy to send you my code to look at.
