Well, heartbeat monitors the public interfaces. So my thinking was to 
also let drbd use the monitored IPs to make sure drbd and heartbeat 
aggree on connectivity status.
Heartbeat can be configured to monitor multiple interfaces/paths. So i 
wanted to use drbd with multiple paths. But this is probably a feature 
not even yet on a wishlist...
