Hello Christian,

All I've done so far is a pure-python wrapper (to run under IronPython)
that uses a vanilla build of the Python.NET dlls - so it sounds like
you've done an awful lot more than me!

Using this approach *should* be more efficient than exchanging pickles
though. It already allows you to access CPython extensions though, which
is great.

If we decided to go ahead we would probably work on PyObjects to make
them behave more like their IronPython equivalents.

Our goal (whichever approach we take in the end) is to allow Python code
that uses CPython extensions run unchanged in IronPython.

If anyone is interested in this you can get the details in my blog entry:

All the best,

Michael Foord
