Thanks for the input.  This is the kind of information I was looking for.

Here's my current proposal (which is very close to Fernando's I think 
with one nuance).

scipy --- core facilities

gscikits --- For GPL encumbered packages regardless of origin or destiny.

scikits --- For BSD third-party packages.  These may be packages with 
wide-spread appeal with a different calling convention than scipy or 
packages that the developers are not done with or just want to keep 
their own release cycles.  Code may come out of here for inclusion into 
scipy, but it will do so using:

scipy-somepackage (imports as scipy.somepackage but is distributed 
separately) --- Packages that will soon be released with scipy but for 
now are being distributed alone because they need a faster release 
cycle.  These packages involve the input of SciPy developers more than a 
scikits package might.

It sounds like your code would live in scikits and then if parts should 
be taken into scipy then they would be through the scipy-somepackage
