Hi, I actually tried Avahi also at first, but was having a lot of difficulties setting it up to my actual target environment (Maemo platform, based on Debian, and used on Nokia 770&N800 devices...). Probably this is anyhow an issue of Debian network configuration, so maybe I'll ask the lists there also. I will later utilize Avahi, if possible, so thanks for the code snippet. :) And if anyone knows what might be the propblem with Pyzeroconf and my dear Ubuntu, please tell me.
