The "use it like a book" has been here before. And in this case, it's like a lot of licensing I had early in the Netware / Win 31 era where you tracked the number of copies being run at one time.

However it's not something that I've seen lately.

the All-Access, however, isn't like this. It's a license by user or machine, but it allows you to use any tool. So if I want ER/Studio for the architect, DBArtisan and the Rapid SQL for the DBA, DBOptmizer and Delphi for the developer, I can All-Access all of them and if they need one of the other tools for a day or two, they just run it. No licensing issues.
