Thank for a fruitful discussion.
I think I can recall that there was a discussion, but no details :-) At any rate, long time ago I had a three node test cluster on Debian Etch with virtual IP addresses (using IPaddr). Haven't tested the setup much, but haven't noticed any problems either. In particular, the IPaddr resources didn't fail. Or did I misunderstand your question?
