If you care to set up a computer on stage the software Circular Logic  
seem to do that i real-time. Below I'm pasting in an earlier post to  
this list by the application's developer Michael Stauffer, so you can  
read up for yourself and eventually follow the links to watch the  
demo movies.

Regarding the tempo track and re-clocking functions of Logic I have  
used them quite successfully for recorded audio, but I wouldn't even  
think about trying it out for a live audio input. Actually I have  
found, when producing recorded music, that I get better tempo sync in  
Logic, to a recorded piece of music, when listening and simply draw  
the tempo curve on the screen exactly the way I would have played it  
if I was a drummer. Now I'm even a lousy Virtual Drummer, so this  
method takes a lot of time. But it's better because you can regain a  
little of what is lost in any tempo following algorithm: the human  
perception and implementation of gestures (that's where the fun is  
IMHO). Sometimes it feels good to bring up the tempo map just a  
little bit before the recorded live audio goes up in tempo and vice  
verca - only to balance the never ending interplay between DRIVING  
and BEING DRIVEN so it kind of creates a "dialogue" between the  
recorded audio and whatever is happening in Logic (the stuff we're  
"syncing").

BTW I presume Live5 does this syncing up midi to recorded material  
better than Logic at the moment.
