Just how many separately hosted grids/asset servers are we talking about 
here?

And how many assets?


SL, sorry to keep bringing it up, but its an important usecase, has 
20,000 simulators and some
ludicrous number of "assets" to deal with. If there's no local caching 
of assets on any other grid,
permissions allowing, then the SL servers would be expected to be asset 
server to the metaverse
and they already groan under the strain of talking to the limited SL 
world. The metaverse is
projected to become 100-100x larger than Secondlife. the AWG's original 
mission was to try to
desing a SL-like meta-grid that would handle such "scary numbers." We 
can't just handwave
the issues away and suggest that existing systems and architectures will 
"just do it" in some way.


Permissions/digital rights  of SOME kind is required for any asset that 
isn't identified as
Creative Commons" and even there, a CC license can vary quite a bit. 
there's a ccREL
(rights expression language) defined just to identify variations of the 
Creative Commons license,
and CC is NOT enough to handle all the possible needs for digital rights.
