There's also a very nice paper about it here.

Just to keep the record straight, the Capabilities concept is
about 50 years old. It was devised at about the same time as ACLs.
For a number of reasons, ACLs have dominated the field. See here
for a nice historical perspective:

Hi Diva
Thanks for the analysis. I have to admit I have only fastly
scanned the oAuth spec. They advertise that it works for desktop
applications so I assume it should not necessarily be too complex
for the end user and not too hard to implement either. Someone
would need to study / poc it or get a statement from the oAuth
team. If the viewer acts as users and regions are consumers it
could be that it can be nicely automated and hidden from the
user. This would allow us to use all those identity providers who
have adopted oAuth. Personally I think identity management,
authentication and authorisation are so well known fields that it
would be odd if we had to invent it from scratch. That said we
should not try bend a standard to something which is not suitable
for.
In the end it is important to realise that this is not just about
virtual worlds but all identity management in the net. No user
wants to upkeep separate credentials just for virtual worlds.
Besides web and vws will become more and more entangled in the
long run. If we want to have a system which will fly in the near
future we should stick our identity eggs to same basket with the
rest of the internet crowd.
regards,
Tommi
