The great thing about CPython is that it comes with the batteries included. The problem with IronPython is that some of these batteries just don't fit - in particular, most of the the C extensions don't work. We'd like to help fix at least some of this problem, to help people who use IronPython to use their CPython scripts without having to port everything over to .NET.

Solving the general problem - plugging an arbitrary C extension into IronPython - is a huge project, and we're not even sure we could work out *how much work it is* without a lot of investigation. What we intend to do is to solve a specific problem, to integrate just one extension, and to use that project as a testbed to examine the possibilities for getting other extensions working - and perhaps, in the long term, solving the general problem.

We think that any solution like this will be valuable not just to us, but to the Python community as a whole. And so, we want to make it Open Source.

Right now, we'd really like to hear from people about the following:

   * Who wants to get involved?  We're really keen on working with
     other people on this.
   * Which module should we go for?  NumPy looks like a good start, as
     it gives us a start on getting SciPy working.  But perhaps there
     are better choices.
   * Should this be a new project, or should we be talking to other
     people about getting it into other projects?
   * Which license?  If we're to work on it with a view to building it
     into Resolver One, then it will need to be
     commercial-software-friendly.  Apart from that - we have no view.
   * What is the best architecture?  We're thinking of this as being a
     bit of C# managed code to interface with the C extension, and a
     thin Python wrapper on top.  The module's existing C extension and
     Python code would "sandwich" this layer.  Let us know if this is a
     silly idea :-)
   * Is there anything else we should be thinking about to get this
     started?

Any thoughts much appreciated!


Regards,

Giles
