QUESTION: Cluster Stack!

I was wondering how many people out there use loadbalancers based in Heartbeat/ldirectord/ipvsadm? If you do in Ubuntu Hardy 8.04, have you already considered an update path into Pacemaker based clusters? If you have, would you go for Pacemaker/OpenAIS (The New Technology) or stay with Pacemaker/Heartbeat (Will now be supported by Linbit for an undetermined period of time).

Please, let me know.

Thank you :).

PS. This is just something that I wan’t to know and has nothing to do about with the Ubuntu Cluster Stack Goals!
