More than one instance of Pd.

If you have an SMP kernel, the kernel will do it for you.

Either OSC or FUDI (with netsend/netrecieve)

I do something similar:  I print all the messages I send to the 
terminal, with time stamps.  "pd -stderr >>performance.log 2>&1" then 
some 'sed' magic to remove the print: prefixes and load it into qlist 
with "read performance.qlist cr", then play it back to render in DVD 
resolution.  The advantage of going via the terminal, is that if Pd 
crashes I still have the log up to that point - hasn't happened yet, though.
