[Opensim-dev] oddities with asset storage

[Ryan McDougall]

In a non-SL context, that asset storage is ameliorated over a
distributed asset system, whether it be P2P, or my own local asset
server.

There is a ceiling on the growth of asset copies: any given avatar has
a fixed number of things to wear, a region a fixed number of things to
display, or a human a fixed number of things they can effectively
manage in an inventory.

If you factor in nose-diving hardware costs per gigabyte, and
distributed placement of that storage, the picture doesn't remain
quite as clear as before.

My point is: if OpenSim is interested in out growing SL, they may need
to take a look at how one might theoretically handle various
non-traditional caching schemes.
