We're not alone. Dave McCallum is also doing stuff in this area as is
Ben Bogart somehow. Actually I'm sure, everyone is using some kind of
state saving and GOP. ;)

This problem is not existing in RRADical. Unless a user decides to
save path information inside the RRADical pool (for example the
location of samples) everything is independent of the location in the
filesystem. 

I did it by "abstracing" out the actual "saving", which is now called
"caretaking" and done by various caretakers. In fact, if you look into
the current CVS I already work on a state saver which doesn't save to
the filesystem at all, but can save *into* an OSC connection, that is
it send the whole state to a network connection.  Other caretakers
like for example a CVS checkin caretaker are also possible.

Two state files for the same Pd patch. For example I have the
beginnings of a performance patch at
http://footils.org/pkg/showcase.tgz which contains some samplers, drum
machines and an FM synth. I can play various tracks with this by just
loading another state file into the pool. It's like a sequencer where
I just load another score.

Ciao
