The other problem with RRDs is that they generally require you to have
access to the files themselves to do anything useful with them. When
you consider a reasonably loaded collectd server pulling in lots of
stats, adding graphing on top of that is just going to slow you down.

Comparison (like stacked load averages) and correlation (like cpu
usage vs network io vs ...) are things i'd like to add to Visage. The
infrastructure to support it is there, just need to write the UI. ;-)
