I am pretty sure the answer to this is a resounding "no".

I also think you should look at some other sources for licensing
decision info. I think you'd probably find quite a few people in the
Open Source world who'd question whether the OSL and AFL are the be-all
and end-all of Open Source licensing.

There are a few other good resources for evaluating licenses. The Free
Software Foundation has a list of Various Licenses and Comments about
Them. Larry Rosen has written a book about Open Source Licensing:
Software Freedom and Intellectual Property Law . And there's a book from
O'Reilly and Associates called Understanding Open Source and Free
Software Licensing . I think any of these would be a pretty good start.

It depends on the application. Is it important to you that your code be
miscible with GPL code?
