Whee. This is an interesting site. I've been lurking here for a few days. The trust metric is a really interesting idea. I remember discussing something like it with Slashdot comments, though the goal was different. Our idea was to change moderation to a basic "like it/ don't like it" choice and make everyone a moderator. The system, through a probably order n^3 algorithm, would assign every other user on slashdot a score based upon how similar you were in comment taste. Eventually, the system could "pre-score" comments based upon how others who were similar to you liked him. We thought it was neat, although it would surely kill the slashdot servers.
Anyway, I'm currently working to add cross-platform audio support to ogg123, the command line vorbis player. I started with libao, a crossplatform audio library buried in ac3dec, which was buried in the LiViD archives. I'm having to rewrite it severely so it does not require automake, just autoconf, and so it allows many simultaneous output drivers to be in use. It's coming along nicely, though I'm going to hit a wall soon when I need to test the IRIX and Solaris code. (Unless someone decides to send me a free UltraSPARC.)
