It seems to me that using the name to determine cluster membership would simplify things for the people configuring ganglia.
It would, but when you have 3000+ machines all chattering on the same port that's a lot of data for a machine to deal with. Not only do the aggregating machines have to hold it all in memory, but the gmetad host has to dump all that info into the rrds.
Seperation by port keeps things scalable. Configuration is a bit of a headache but I'd rather spend some extra time planning than extra time dealing with machines running out of memory.
