incidentally i am also pretty deep in the process of building a modular 
sequencer that saves the state of all the objects in a song using 
[maphash] which suffers from the same "saves the textfile releatve to 
the pd dir, not the patch dir" problem.  how can you share a little more 
detail on how your solved this issue?  also, what advantages does the 
[pool] object have over [maphash]?
