Yes. From x86 linux:

libvorbis.a     178K
libvorbisenc.a  1.1M
libvorbisfile.a 24K

libvorbis.so.0.3.0     170K
libvorbisenc.so.2.0.0  1.2M
libvorbisfile.so.3.1.0 34K

stripping debug info reduces libvorbisenc.so to 1006K.

My guess would be it's all the mode tables. Are you worried about
distribution size of on-disk/in ram size? They ought to compress fairly
well; if it's the second you could implement some kind of compression
scheme within the library.
