Anyone have any insight into this situation? To be shipped on the OLPC platform, code and binaries must be a few things: 1) Open Source 2) Free of known patent encumbrance 3) Redistributable/transferrable Yes, you can ask the MP3 licensing association for a license for your MP3 decoder/encoder, even pay them a flat fee of $50,000 for an unlimited license IIRC. But that license is _NOT_ transferable to other parties. After having paid for that license, you can distribute the MP3 software to your friend, but that friend cannot then give that software to another friend without buying a license himself. And that's the problem with MP3 and open-source. As a small digression, most standards are usually RAND (Reasonable And Non-Discriminatory). MPEG (and hence MP3) is such a standard. That does _NOT_ mean that the standard is free of patent protection, or that licenses are not required to implement the standard. It simply means that the owners of the intellectual property on which the standard is based cannot charge everyone a wildly different amount of money, and cannot refuse to license the technology to somebody just because they don't like them. But that doesn't mean the standards are free and clear to implement and redistribute. Dan ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Vorbis for lossy music, FLAC for lossless music, and Speex for human voice (very useful for podcasts). And best of all, they fulfill all of those requirements you mention. Keep spreading files in those formats for a world of Open Media. -Ivo ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
