commandline ogg encoder oggenc2.3 available at rarewares.hydrogenaudio.org/ogg.html. Use the 1.0.1 if you're looking at Q settings under 5, use the GT3b1 for Q=>5. (Use the external encoder options in EAC.)

oggdropXPd is a cute little gui tool for encoding and decoding ogg files.

There's a whole bunch of other ogg vorbis tools there too, including vorbisgain. Rob is aware of vorbisgain (ReplayGain) and it might not be impossible for eventual replaygain support at some point in the future.

The guys who maintain the rarewares site really know what they are talking about.
