I don't know about the security aspect, but think they'd be equal.
Comparing creation time / space efficency, blocks clearly win
I'd _guess_ that objects are faster for lookups, but I don't know.
(And using hashes instead of blocks is the worst for creation time /
space, but I don't know how it works for lookups.)

But there would be a problem when it comes to adding a new group to the
object! case, I don't know if this might pose a problem in this specific
I hope that helps,
