Has anyone looked at the new python license yet? They've been working
with FSF and Stallman to make one that's compatible with GPL. Last I
checked, they were trying to work out one last sticking point.
Unfortunately, I'm not familiar with the terms of that license. If anyone
knows anything about it, and whether or not it would be a *good thing* for
biopython, please let us know!

Yes. The GPL is mostly targetted towards end user applications, where
modifications are generally bug fixes or feature additions. The core
purpose of the application isn't changed. For libraries, it's a bit more
problematic since libraries are usually the infrastructure, rather than
the actual "meat" of the program. There's many different applications
that can be built on top of the library, and it seems odd to me to require
people to GPL anything that uses a library.
