At second glance: it's not going to be that easy. The built-in player
makes use of mutex-locks which would need to be replaced with a
[lock-free] ringbuffer (Adding JACK I/O is still trivial but without
lock-free buffers paulstrech would be able to block jack-processing and
cause x-runs).
That'd be a good job for someone who wants to get started with JACK and
C/C++ programming.
I'd be interested.
It would likely take me some time though, and maybe some guidance, but
it's something I want to learn. I dabbled in C but can only read simple
code. I start to study computer science next week, which will give me
access to the library at least, to K&R and a bunch of others.
The lectures at university are mostly in java but C is required at some
point, and I guess it's better to start learning it sooner rather than
later, besides, it seems to be needed for all the neat audio stuff ;)
So yeah, I guess I should get the code, put it in a git repo and just
start hacking...

I don't know what Paul is up to these days, but I do know that he made
some additions to ZynAddSubFX fairly recently (the main development
of this is being handled by others now).
I've exchanged a few emails in the past, and found him very
approachable - but do bear in mind English is not his native language!
Also, he must be getting on a bit now ... at least in his thirties :P
You might also like to chat with Alan Calvin (Cal) who is working on
Yoshimi, a derivative of Zyn. and doing special work on improving the
jack interface.
