The easy way. How else?

I would like to try out your work under perl.

But the dynamic libs loaded by python allow invokation
of the gpled code from anywhere. 
If that is not a problem then I can wrap the VM in a
perl DLL?

The mapping of values from one system to the other?
Thi is an iteresting problem I aggree.

As soon as you make a GPLEd dll, only gpl code can
call it. the entire program becomes gpled. According
to the  GPLe faq.

So what is the problem?

It just turns out that we have the same license on all
this code, and you will allow some people to link some
modules to them and other not? Untill someone makes a
clear statement on what is possible, what am I
supposed to do?

I feel that my perl work get stopped because of
licensing and you go on even if there is no difference
between the two, only that you dont *want* certain
modules to be linked. 

The linking of perl to the cscc is the same as to the
il_execute from the licensing side. just because you
dont like the idea does not mean you can stop it, only
complain. 

Change the license to reflect you wishes and dont play
games.

If you want any real contribution, make a level
playing field, clear and consistent rules for
everyone!
