Dear Norman,

Apparently you had input from VOSpacers already. Hence, what remains from a data provider viewpoint is to underline the cases [Virtual-file permissions], [Shared, writeable (virtual) file)] and [Quota on VOSpace storage] which are generally related to file system operations.

I'd happily dismay those who look for complex cases :) As you say, an implementation is not that simple since it has got to be robust and scale.
Just for your information: ESO is in the process of becoming a Registration Authority for its staff members and is adopting the academic policy of the global IGTF (www.gridpma.org) through its European branch EUGridPMA. This implies use of X.509 certificates which appears to be in line with the authorization packages that you evaluated.
Cheers,
Markus
