Quick conclusion but, I wouldn't call it a correct one.
There is even no irony there.
SM and universes are not the same thing.
If I want the service of SqueakMap I want that because it has been proved
useful in
the past and then I do not want to deal with another catalogue
which has been cobbeled together in a few days and is not proven.
In the TeX/LaTeX-world I have a central catalogue of everything. There
are several physical servers but from the logical point of view it is just
_one_ server. ( http://www.ctan.org/ )
The same thing applies for the Perl community ( http://www.cpan.org/ )
which by the way has many more packages than Squeak and they
didn't see the necessity for a fork of their catalogue. And BTW it
helps do book CDs and things like that.
CONCLUSION:
A general catalogue is a service to a whole community and
a physically reliable service is what is needed. So the conclusion is
that we need a mirror of SM in the future (not a duplicate effort
concept-wise).
In the meantime if the downtime is not long it is not a big issue.

Hannes
