Oddly enough i was just thinking about this and wondering why no-one
had written one yet.
I understand the logic for making it into a quorum plugin, but I would
really love to see it useable in both ways. To me, you just can't
beat the simplicity and flexibility of making it an RA (whereas I am
somewhat cautious about involving the CCM, especially in it's
currently unmaintained state).
