I'd also be generally interested in hearing about any scaling work
that's been done. I'm trying (probably in vain) to get pcp adopted at my
company. we have thousands of hosts per cluster, and would need massive
scalability. I'm not sure if it's possible. I may be able to aggregate
the subparts of the cluster (front end, back end, logger) into their
own sub-clusters, but still, thousands is hard.
