Speaking about the Fortran part only, I honestly don't expect anybody 
else to do major rewrites of the f2py wrappers (.pyf files) while this 
is going on; any (unlikely) minor tweaks can readily be merged (provided 
a decision is made for SciPy on CPython to move from f2py to fwrap).

I can try to keep the replacement of f2py with fwrap in a seperate 
branch that could potentially be merged without taking the other stuff 
from the .NET branch. Not sure whether that will succeed yet, but it is 
definitely worth a try. So perhaps one can have two or three branches 
with different kinds of changes rather than one large one. Replacing 
f2py with fwrap seems to be orthogonal to changes that has to do with 
changes necessitated by the refactoring of NumPy, but I don't know yet 
whether that will hold true in practice.

(For non-Fortran it would be better to start a new thread on the .NET 
refactoring in general and ask Jason McCampbell, I can't tell.)
