I built an RPM for FC5 but I can’t find any way to contact the developers to tell them about it, so if any of you reads this and is interested in posting it to sourceforge I’ll be happy to send it.
I built it using the latest stable code with the avahi-howl-compat libraries. Haven’t tried the native avahi patch yet.
Update: the RPM now contains the native avahi patch.
Update 2: unfortunately the admin web interface says that Rendezvous is not supported. Any ideas? (the avahi-daemon is installed and running)
