There's a license called the Affero General Public License which is
basically the GPL with an added clause for distributed use, such as web
scripts, which the FSF consider a free software license; as well as
Apple's APSL. Debian, however, consider these licenses non-free, as the
conditions are based on the use of the software, rather than redistribution.
