CameraSynch2
Hax CameraSynch v1.0.0
Synchronization of multiple avatar cameras.
This script initially needs to be dropped individually in numerous prims, which are then linked together.
However because the script adds a PIN, after its been added once the owner can issue the "update" command to automatically propogate any changes made to the root script into the child prims/scripts.
