One of the interesting things that hit me as “way cool” while using Mandrake 9.1 was the inclusion of Zeroconf (aka Rendezvous) in the network setup wizard. You could configure manually, or you could use BOOTP/DHCP/Zeroconf. How cool is that?
I wasn’t able to test Zeroconf out, as I only have aging Mac hardware (one has a G4 processor upgrade though, does that count?) and nothing that runs OS X. There is a Sourceforge project that includes a partial yet working implementation of Zeroconf for Unix/Linux, but it’s really nice to see something like this enabled by default in a Linux OS.
You can download zcip for Unix/Linux, and there is also a Debain package. It appears that Mandrake also uses zcip. A quick googling yields no RPMs for Red Hat, but it shouldn’t be too hard to compile from source. At the time of this writing, I can not access zeroconf.org, but it is/was an informative site.
