[Opensim-users] Parcel Archiver?

Wow, it is really starting to sound like we need a more robust tool for
backing up, restoring, merging, and upgrading regions and parcels. The use
case I have is my standalone has a region that has been subdivided into 32
parcels. Each parcel is an office space where the user can personalize their
own space. As people roll on and off projects I need to be able to backup a
parcel and replace it with a blank one for the next user. If the original
user comes back for another project I need to restore their office space to
either the same spot or another spot that is available. I seriously do not
want to backup and restore entire regions for each change of a tiny parcel.
Also if you rent out an event space think of how easy it would be to just
bring events up and down based on each time slot. This would give OpenSim a
really cool and useful advantage.
