Well, it can't be trademarked.  But it has plenty of meaning to the
community.

Probably not, but anyone can propose it, even you.  Of course, if OSI
wants modifications, you won't be able to make them.

3 says that BBN gets to reuse any derivative works you make, even ones
that are closed-source to everyone else; it's an asymmetry clause similar
to the one in the NPL.

9 just says that you agree that the stuff you contribute as your source code
really is your source code and doesn't belong to someone else, like your
employer.

I see nothing (IANAL, TINLA, IANAOSI).

The license is a variant of the Artistic License used for Perl.
