[shell] + ipconfig ?

i guess the problem is, that most computers are virtually multi-homed 
(having multiple network cards and IP-addresses attached to them): very 
few (actually not true: more and more gaming computers are shipped with 
dual ethernet cards) computers have multiple real ethernet cards.
however, apart from your normal network card (eth0) bound to whatever IP 
you assign to it, you have a loopback device (lo) bound to 
so you have to make a decision which network device you want to transmit 
as your "local IP" address. (in most cases, is not what you 
want to transmit)

i would use some magic in a startup script which queries the IP address 
and then saves it to a file or sends it to pd using the "-send" flag 
when starting pd (i would prefer the later as it needs no additional files)
