If there was enough resources to pay someone very familiar with numpy
codebase for a long time, then yes, it could be useful - but I assume
that's out of the question. This would be very expensive as it would
requires several full months IMO.
The PSF could help for the point 3, by porting other projects to py3k
and documenting it. The only example I know so far is pycog2
Paying people to do documentation about porting C code seems like a
good way to spend money: it would be useful outside numpy community,
and would presumably be less costly.
