Thanks guys! Your suggestions have been very helpful, particularly the ones from hossman and tomhukins.

I think I have an idea for an implementation that would be both easy on queries and on updates. Basically, instead of using an INT column for my ids I'd use a VARCHAR. Then the current version of every object is just the id number, say "1024". When I create a new version I append the version number creating a new id - "1024,1" for version 1 for example. This makes creating a new version as simple as cloning records in all affected tables under the new id. SELECTs and JOINs stay simple since selecting on the id as-is always gets you the current version.

So, how does that sound? Am I missing something that will cause me premature hair-loss later?
