Rolling upgrades are not supported by Oracle yet. Also, it depends on what do you mean by a rolling upgrade. If you mean a one-off patch then it is possible to apply it if you have individual homes but what about an RDBMS upgrade? How would separate homes help you there because you will have to shutdown the database.

        Because if you have a single, shared ORACLE_HOME, you can't do rolling upgrades with RAC.

		Nope, sorry, this is determined by whether the ***OS***

(i.e. not the database) supports a clustered file system or not. I suspect this is something you already know, since you sell one. :)                 

                Sorry, couldn't resist.                 

                Seriously, where a CFS is supported by the OS, why would you do anything else for the ORACLE_HOME?
