[cap-talk] Fwd: [cors] TAG request concerning CORS &Next Step(s)

[David Barbour]

Another feasible design is to use time-expiry caps... i.e. offering a
capability to use Google's ticker for a period of time, with regular renewal
from Acme. Acme would be free to cut off the expenditure at any time if a
user is discovered to abuse it, and can use a small pool of caps for a
larger group of users (using more than one cap allows them to quickly
discover abusers, but avoiding one cap per user keeps the communications
price down).

That's the approach I've been pondering for a related problem, anyway: in
ocap-secured gaming, how do you ensure that players who obtain an ocap at
one point - e.g. to listen to the audio feed for a region, or see the
contents of a room - will lose that cap upon the avatar leaving the region?
My thought was that the environment would regularly broadcast caps to
avatars in the region, allowing the older caps to expire. This would reduce
the incentive for 'cheating' because a cheating client could not maintain a
cap without the cooperation of the broadcast source... but it would also
have a relatively low overhead.
