I wonder - was it with the more advanced stuff or the simpler haresources?

haresources is indeed trivial, the other thing just didn't work
(CentOS 5, x86_64, xen 3.0.x guests, doing VIP for the simplest test
case but haresources is used in production for drbd, databases, http
servers, vip's, LVS, monitoring stuff (collectd, monit), and
home-grown software).

If you have a pointer to GOOD documentation/tutorial about the cib and
friends then I'd love to see it.

Thanks,
