Hello Jordi,
Cool thing the possibility to do tcpdump in pd!
I was trying to build the version 0.0.3 on osx and i run into many
errors due to some difference in headers in osx and linux:
iphdr and icmphdr struct were not defined in osx,
so i added their definition.
and tcp and udp source and dest have different labelling:
http://en.wikipedia.org/wiki/Tcphdr
(the bsd standard seems to work on both platform though)
so i changed them.
it manages to compiles and now seems to run fine!
except that i have zero hexadecimal data on the outlet10... and i'd love
to have them.
maybe it would be nice to use the general ip struct definiton if possible?

attached is the diff between your file and mine.
thx to share your work,
n
osx 10.5.8
pd-extended 0.42.5

Hi, I've made a patch to visualize on a world map the location of
remote hosts that connects to our computer.
Video demo: http://vimeo.com/15138625
Download the patch (It's a "dirty" patch) but I expect I works for
most linux computers...
