Vorbize has always been able to tag, and there are now patches to OggLAME to 
do tagging.  All the plugins can hadle the tags.

Second BETA is slated for this weekend, along with VBR 96, 128, 160, 192, 
256kbps stereo modes.  1.0 final (with CBR) is optimisitcally scheduled for 
the week before LinuxExpo.

*shrug*  Then it's no improvement over the current mp3 situation.  Is it
filterbank based?  If so, we're even worse off as there's no encoder source and
it's still infringing FhG's patents.

Note that Vorbis would be just as fast as mp3 in decode if we had an iMDCT 
that was as fast as what other codecs are using.  I wrote the one in Vorbis 
many years ago when there was no source available for such a beast and it's 
not particualrly fast.
