Actually Tim, I have proposed this use case a long time ago already.
And have also already repeated it when Michael entered the list:

From a mail by myself in March 2003 (oh yes):
Well, one thing I have been waiting to see is a possibility to send tempo to
the host. For example: I want to make a tempo tracker plugin that extracts
the tempo from an audio stream and have that being used as the "master
tempo" to which all other things are time-sync'd in a musical sense (good
for live performances and music that calls for easy tempo fluctuations).

I just thought repeating this exact same thing AGAIN seems a bit overdoing
it right (especially when Michael also proposed the same use case)?

But I *can* get more precise if you like:
- Guitarist and percussionist are playing live.
- Other music parts (synth arpeggios, extra percussion, ...) are
pre-recorded on tracks in the sequencer.
- While playing, the percussionist puts in small tempo fluctuations to give
the song a better live feel (speed ups, slow downs, hesitations, ...)
- The guitarist can follow that as he is playing live too.
- The sequencer tracks also follows that because a plugin is mounted on the
incoming live audio from the percussionist, and all other parts of the song
just follow the live tempo fluctuations.
