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 case, though. I hope that helps, Ingo
