I have been mystified by LL's failure to address this for the full 7 years I have been on SL. Yes, TAR/ZIP and Archive by all means, any means, if it will finally mean an avatar can move from one region to another without dragging the full load of a 20 to50K item inventory hit to the servers at once. Protected archives, even if it requires a small fee, would make SL more responsive, and emmersive. I fully support your efforts. The ball is squarely on LL's court to tell us if/why it can or cannot be done or help.
