Please ensure patent policy is GPL compliant

Dear Sir/Madam,

Please ensure that the W3C's Royalty-Free patent policy is fully
compliant with the GNU General Public License.  I am particularly
concerned about item three of section three in the existing
proposal, which discriminates based on software use.  Please
eliminate this clause.

The WWW is largely reliant on free software.  As it stands, the
W3C patent policy will eliminate free software, strangling the
very web that the W3C seeks to promote.
