@pali, I've installed this on my n900 from the repos (-maemo5 package version) and rebooted my phone.

I then installed the Debian avahi/mdns packages on my laptop.

Neither is able to ping the .local address of its counterpart.

Running avahi-discover on my laptop, I can see only the laptop itself.

On the n900, 'ps -ef | grep avahi' shows two processes running okay. And the changes to the /etc/nsswitch.conf file look correct (same as the laptop).

Do you have any idea why it might not be working? I guess I can run tcpdump for multicast packets next, if need be.
