Hi fwrnando,

it seems to be working for me here in my N900, but I had to:

1. Install libnss-mdns as explained in this thread http://talk.maemo.org/showthread.php?t=24578
2. Edit /etc/nsswitch.conf and change the hosts line from:

   hosts: files dns

   to:

   hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4

1. I install avahi-utils package
2. Within a terminal I issue avahi-discover and it shows me the list of local available zeroconf servers, my notebook is avertised among them as "daniel-VGN-FZ21S.local"
3. I issue "avahi-resolve -4 -n daniel-VGN-FZ21S.local" and it gives me the ip of my notebook as expected.
4. "ssh daniel@daniel-VGN-FZ21S.local" works as expected

No no more need to manually look up or hardcode ips in my DHCP server.
