Dean, Are type 1 UUIDs the best ones to use if I want to avoid conflict? I saw this page: http://en.wikipedia.org/wiki/Universally_unique_identifier The only problem with type 1 UUIDs is they are "not opaque"? I know there is one kind of UUID that can generate two equal values if you generate them at the same milisecond, but I guess I was confusing them...
