To expand somewhat on Alexander's reply: No, I don't think so.
Shared repositories are merely an space optimization, and they will
only do any optimization if any branches shares some subset of
This means that there is little point in storing unrelated projects in
the same shared repository.

As I understand it, both file locking, and the size/count of the pack
files in such a shared-across-many-projects would make it suck.
