Most callback systems offer you to pass in a 'context' pointer value.  
You could then pass in a C++ object for the context, a C++ class  
method for a callback, and in the callback, do a cast on the context  
pointer to the real pointer type and do your stuff. I have not used  
Jack, so I'm not sure what support there is for this type of  
integration. It works like a charm for Motif and Apple's Zeroconf  
(Bonjour) reference implementation.
