The reason why I started on this was to help implement reflection.emit.
When the ILAsm code is wrapped in internal calls, and made available
via static linking to the C#, it can be used to implement the
Reflection.Emit code. 

I must say that I find the reflection.emit class model to be bad. I
hope to create a new and better version that superceeds the limited
microsoft based model.

Yes of course. All my software is GPLed, I dont support anyone using
GPLed code to make non free tools. 

If pnet is embedded in a Perl Module, or better yet linked statically
directly into a new perl exe, we will be able to call back and forth. 
Later on we can try and merge pnet and parrot runtimes into on.

When pnet is wrapped, I will be wrapping mono and parrot
then we can start looking into horse trading games. 

The whole idea of a wrapper is isolation, when you wrap mono, you can
also use that wrapper code to help create the mono personality for
