I'm not a PLaneT implementer, so I don't know for sure.  But I would
guess it's all about permissions.  Unless DrScheme were to always run
as a superuser, the only way for PLaneT caches to be shared is if they
were all globally writable.  That would be a big security hole: code
everyone uses, which anyone can write to, would be very easy to
sabotage.
