So does Richard M. Stallman :)

Most users don't care about OSS politics.

And therefore a majority of users should be inconvenienced for a small minority?

To some, not many.

This simply isn't true.  I don't use 'gapt-get' or 'gsourceforge'.
I'd be a bit irritated if I had to fire up gapt-get for X but had to
use apt-get for Y.   Not to mention the potential problem of
collisions (scikits.foo and gscikits.foo).

So you are going to audit the contents of scikits periodically?  Even
if scikits has hundreds/thousands of packages and contributors?

Who are these people?  I can't imagine a business taking 'our word'
for it and blindly using a scikit in their product.  The first time
GPL code slips into a scikit the distinction will become meaningless
and untrustworthy.

The problem I have with 'gscikits' is that if the scikit idea actually
takes off then it will require an army of people to keep scikits free
of encumbered code.  We cannot trust casual contributors to do their
homework and keep GPL out of their scikits.  The distinction is only
as good as the certifier.
