hi,
After having it running for a few days I think it's reasonably ok to share with the rest of you, there is now an extern to talk to the dmx4linux driver (-> http://llg.cubic.org/dmx4linux/ ) from pd. I wrote it for an installation (the same reason I wrote the netreceive patch), it's neither full featured nor especially well tested but it could serve as a starting point to use dmx with pd running linux.
get it here -> http://test.pilot.fm/pd/externs/ more info on dmx can be found here -> http://www.euro-pa.be/dmx.html
special thanks to Michael Stickel, for writing the linux driver and his kind support.
ah yes and there is an exceptionally boring screenshot, but since it's there anyway -> http://test.pilot.fm/nolink/help_dmx_pd.png
regards,
