It is certainly true that "global" broadcasts don't scale well.  But
broadcasts (and multicasts) are very useful within "local" LAN
domains.  I also agree with the direction of your idea for rwho
services.  But I think the real bug in scaling is building a bridged
network with 30K+ nodes.  To scale to that size you need to route.

More importantly, I'm not sure we should worry too much about 
"local" protocols such as rwho scaling into overgrown bridged 
environments.
