[PD] [netsend] unix socket because of [comport]

[patrick]

hi,

i'm looking for the best way to use netsend / netreceiving between 2 
instances of pd (1 with -nogui) running on the same computer.

someone mentioned a way on linux to use the unix socket with netsend / 
netreceiving. i didn't find any information on the mailing list archive 
(http://lists.puredata.info/pipermail/pd-list/) or in the help file of 
[netsend]

someone could ask why i need to run 2 instances of pd on the same computer? 
last time it was for gem (-noaudio) + audio (-rt). this time, it's because 
of [comport] adding glitches to a simple [osc~ 444] - [dac~].

any advice greatly appreciated!
