Note that Paul's script relies on LAME to do the bitrate normalization,
so obviously, you have to have LAME installed.
There was some discussion about the performance impact of re-encoding
every outbound track, but I don't know if anyone discussed their
experiences. Paul, is this a big resource hit?
Thanks,
Chris
