My lay knowledge of US Trademark law and case history and reading of
http://www.python.org/psf/trademarks/
suggests that 'nothing stopping' is exactly wrong. I believe the 
trademark has also been registered in Europe.

As usual, 'I am not a lawyer', but if Christian wants to push forward 
with using 'Python 2.8', I suggest that he consult the PSF Trademark 
Committee and lawyer first.

But it is *not* unrelated.

Yep, I do. 'Stackless 10' would have no issue.

I think two unrelated issues are being mixed together in this thread 
that really should be two separate thread.

1. Compiling Windows CPython x.y with more than one compiler. This is 
not specifically a Stackless issue or even a 2.7 issue. If 3.4 is 
released compiled with VS2010, there will be people wanting it compiled 
with VS2013(12?). And vice versa.

2. Public releases of new Python versions based on 2.7 that are not 3.x. 
How they are named is an issue regardless of what Windows compiler is 
used, if indeed a release even uses one. In my view, either no one 
should be allowed to call something 'X Python 2.8' (or any unofficial 
x.y), or everyone should. The latter might mean that we see Stackless 
Python 2.8, Ubuntu Python 2.8, RedHat Python 2.8, ActiveState Python 
2.8, Enthought Python 2.8, etc, all different. I prefer no one.
