I'm interested in monitoring the hell out of the vservers (cpu %,
loadavg, tokens, memory, network traffic, processes, disk i/o, you
name it) so I'd be willing to help (please note I haven't used neither
netlink nor relayfs yet but you learn all your life, don't you?)

I have a little patch to collect per-server disk usage stats (somewhat
like /proc/diskstats) but I dropped it from my kernels during the
recent debugging frenzy and I'm a bit reluctant to apply it again - a
bit too intrusive for my taste and I don't know whether it's SMP-safe
really. If anybody is interested, feel free to drop me a note.
