I'm unsure about this.

We never pack the wikis storage:  that difference in policy is
actually the reason we moved wikis to a separate storage in the
first place.

The other thing about the zope.org storages is that they are all
served by a ZEO storage server;  hence, I think it would be
feasible to create an additional ZEO client, which used the main
site's "sub-storage" as its own main storage;  one would then be
able to pack it (I think), while leaving the main site running
(but more slowly during the pack).
