yes i've been looking at your stuff -  that plus iemguts. the only issue with whatever solution i have to provide is that i want to run it with libpd and potentially sell the results on the App Store, so licenses have to be MIT or BSD and not GPL. all of this because i'm considering the complexities involved in putting together a dynamic game audio engine in PD, and sending messages to it from either a separately programmed GUI or an engine like Unity. i'm still in the preliminaries of just thinking about ramifications and it's just getting more and more complex as i think about it.

as for other responses, i think keeping track of it externally  (i'd be inclined to do this with Javascript and not C) is a good idea. since commands to create and destroy objects come from outside i should be able to keep track of their creation order. everything is still early days, both in terms of my basic understanding of PD and my understanding of the most efficient way to deal with it.

You can encode object types and connections in such an object I guess -  this is a bit like writing an object that makes a map of Pd patches, and you could encode the connections as well. Perhaps iemguts does this although I don't know it that well. (it's the patch itself we're trying to query after all - what objects, in what order, and how are they connected, and in what order).

i guess this is also just what dyn~ (http://puredata.info/Members/thomas/dynext) tries to do.
