Hi Mark,
(disclaimer: I work for Fluendo)
I didn't understand your comment about multimedia. First of all, I have no idea how any of the licenses you mention could solve the multimedia problem.
Second, there are open source players matched to the Fluendo codecs. The codecs plug into GStreamer, GStreamer is LGPL, and any free software application can link to GStreamer and use the codecs. Totem does it, Rhythmbox and Banshee do it, and so do a host of other applications.
As for the codecs being proprietary, nothing that can be done about that. For some formats, by definition, you can't have both "legal/licensed" and "open source/free software". But hey, you pick either one until those codecs are obsolete. »
