It automatically will throw away frequencies higher than 20khz?  The 
reason I'd like to try using Vorbis with a high sample rate is because 
the files would be smaller obviously.  Not for archiving of perfect 
quality versions though.  24-bit 96kHz wave files take up a lot of 
space, about 16MB per channel per minute.  Although I'm more interested 
in having 24-bit bit depth than the higher sampling frequencies.  I 
think the higher headroom is more noticeable than the higher sampling, 
although that may just be because my speakers probably don't go much 
past 20kHz.
