In normal Python you can call Class.__subclasses__() to get a list of 
subclasses. I haven't tried this with .NET classes on IronPython though.

You can either patch __builtins__.__import__, use the ihooks module, 
implement a PEP 302 import loader *or* use the IronPython Platform 
Application Layer to control how IronPython imports are done (this is 
how IronPython on Silverlight does imports from the xap file).

All the best,
