Ah, Bill Crow has provided some and concerns about the methodology; it's nice to see him posting again. Given the very flexible licensing compared to other windows media, I don't have the antipathy a lot of folks seem to toward the new format. I mean, free until 2010 and for anything running on windows? (I wonder how this applies to the cross-platform libavcodec, which I couldn't figure out even after rereading the full license agreement.) I doubt it'd ever be like the unisys debacle, since they're being very upfront about the terms. I'm waiting to see what support it garners beyond the operating system and how good it really is, when I'll make my choice.
