I wouldn't like to de-rail this too much as there is a very active Pd 
mailing list. Anyway.
Pd can take a while to get into, but I can say that Pd works very well 
with Jack and I never had big issues. Of course you should keep in mind 
that Pd is a programming language and enables you to do whatever you 
want, even fill an array beyond your ram size et. sim. with great power...

It is absolutely doable, near to trivial with the above mentioned 
[sigmund~] external. Again if you are really up to it it would probably 
be better to discuss this on the Pd-list which is usually very friendly 
and supportive.
If you want I can post somewhere (tm) a basic patch.
