Re: [ogpx] Decoupling simulation services from land for VWRAP scalability

[Carlo Wood <[e-mail]>]

It is possible to move "policy" (like 'have to follow the rules of physics')
to the viewers, and enforce it based on statistics: Assume that most viewers
are the official implementation and react predictably, and simply let
the viewers 'vote' to establish who is breaking that policy.

For example, 6 avatars are in a room. 5 run approved viewers, one is using
a rogue viewer. The one with the rogue viewer walks through a wall. The
other 5 detect this and (automatically) inform the server that this viewer
broke the accepted policy. The server bans the rogue viewer. That leading
by itself to keeping the number of rogue viewers small and hence the
system working.
