To me this looks as if there is essentially no difference
to people distributing their projects independently of scipy
(and outside of its name-space).
I still like this for two reasons
a) it would bring scientific python projects under one umbrella
b) the (hopefully) simple user installation:

Sounds very nice! I have no experience with eggs:
where do these go when a user cannot install them as root?
(Of course, a  PYTHONPATH modification should do the job.)

(If I disagree with this point, would this
decrease my-already-in-the-negative-I-presume opinion budget? ;-)
