Does pip have the option to limit package installation by licence type? Plus,  
some packages may be "DSFG Compliant" but may have a licence that isn't FSF  
approved.

Your solution is to create a repository for packages which requires hosting  
the packages and maintaining them. Or you can just blacklist packages that  
are not free instead of having to handle potentially thousands of packages.  
I'd prefer to have a list of packages that can be updated and pip checks that  
when a user tries to install.
