[IronPython] RE: Inheriting Python classes from .NET classes

You found a valid bug in IronPython. One of the reasons this doesn't
is that we currently don't support inheriting from .Net classes with no
public constructors. That part is pretty easy to fix. However, there may
be other roadblocks (beyond the one I found so far) to overcome to get
your case working. The reason I think so is that MarshalByRefObject is
a special class in the .Net framework and IronPython may not be ready to
handle all its facets. We are working on it though.

Thanks for the bug report!
