Access control use-cases

Greetings,

I'm going to be doing some work on access control and authorisation, initially within the AstroGrid context, but it would I hope be applicable more broadly. I'm gathering use-cases, and have a few collected at <http://wiki.eurovotech.org/twiki/bin/view/VOTech/ AccessControlUseCases>. Some of these were extracted from this list's archives. If I've missed your favourite one, please do shout. Or if I've missed your least-favourite, most headache- inducing, one.

I was talking recently to some folk who are working on policy management (partly, though not exclusively, in the context of the semantic web). They seemed rather dismayed at how simple most use- cases were, since they were aiming at a pretty powerful system.

So let rip. The ones I've got so far are probably fairly easily manageable (in terms of the logic and delegation involved, rather than necessarily their implementation in a live system).

Thanks!

Norman
