But does this not apply (from rfc1602) ?: 5.4.1. All Contributions By submission of a contribution to ISOC, and in consideration of possible dissemination of the contribution to the Internet community, a contributor is deemed to agree to the following terms and conditions: l. Contributor agrees to grant, and does grant to ISOC, a perpetual, non-exclusive, royalty-free, world-wide right and license under any copyrights in the contribution to reproduce, distribute, perform or display publicly and prepare derivative works that are based on or incorporate all or part of the contribution, and to reproduce, distribute and perform or display publicly any such derivative works, in any form and in all languages, and to authorize others to do so. My understanding is that even if they've patented MPPC, the fact that it's an rfc that doesn't explicitly state that you can't implement it implies that M$ have already granted me the right to write the code and publish it. > -GAWollman > > -- > Garrett A.
