Anyway I am not going to port polypaudio to glib now.

Is there a need for having both libsamplerate and a new library
around? What is the advantage of gestreamer's resampling code over
that of libsamplerate?

What I'd really like to see a libmix for mixing audio.

You would lose sample caching which both esound and polypaudio support
that way. Or does GStreamer contain an abstraction for cample caching?
