First solution: Write external scripts that check the coexistance of the services on a node and reconfigure them accordingly. Second solution: Hack the RA scripts and add such a check to the start section. Basically that means to derive your own RAs from the existing ones. Please keep in mind to revert the config changes as soon the services run on different nodes again.
