Yeah, I learned about it from Fabio, thought it would be a cool idea,
and eventually we sponsored Harald to make it happen. It's shipping in
SLES9, and we're adding full support for it in the 2.0 heartbeat cluster
It's meant to complement the LVS / mod_backhand based approaches.
If the proc file IO for communicating with the module goes away in
favour of a commandline based add/list/remove/etc interface, that would
just help to tidy up our code, so it's OK with me.

Yeah, but with this they get a whole lot more ;-)
