Hi, all. I might have misunderstood the Racks place in ZPatterns, but anyway... To me, this sounds like a really, really cool idea. If we passed the User object along to the Racks (which is what it does now?), and let the Rack (GPG/PGP Rack, that is) have access to either an external or internal keyserver, and the User object contained a pgp_user_id, then the Rack could use that attrib (and since it would be an AUTHENTICATED_USER) to sign/verify/encrypt/decrypt information within that Rack. The Rack would also store all previous revisions of itself, so that data never would be overwritten - and one could see who, when and what was changed (on attribute level, since Racks control each attribute?). Or maybe this should be on SheetProvider/AttributeProvider level? I guess it would suffice with a class that they could subclass. I would be happy to implement this (although, I won't have time till February or later) - I just to make sure that my head is screwed on the right way here. By the way, go ZPatterns.
