Another scripting language implemented into Python itself?

I don't see how that would equate to something that the original 
programmer should be concerned about. You could include a bit in your 
licensing scheme that voids all support on code that has been modified 
in any way. You shouldn't be obligated and no one expects you to support 
something the end-user has mucked with.

You could trivially enforce this by keeping checksums of all the system 

In any case, there's nothing you can really do to "secure" your code. 
This is true of any language, C, C++, and especially scripting languages 
like Python. Anyone who has the determination get at and modify the code 
probably will.

The only time where I can see someone using another language in place of 
Python for a scripting language is just domain-specific factors, e.g. if 
you need the extension language to be easily used non-programmers.

Just a thought.
