Florian, it is very possible that I overlooked some valuable documentation. It is also possible that things have improved since I tried it last summer.
However, at present, my question was to locate and consider alternatives to drbd and heartbeat. I will peruse the links that you provided, as, probably, we will end up using the Heartbeat setup that I created as a replacement. Functionality of Heartbeat 1.0 was fully sufficient for our needs.
