I believe the answer is no, but looking to definitive verification – a single Presence server cannot provide this service for multiple clusters, can it? Meaning, the customer is wanting to avoid having to stand up a Presence server in each of four clusters. (No cross-cluster presence is required – just the ability to “register” the Presence server to multiple CMs.)
Again, pretty sure the answer is no – furthered by the fact that Presence will now be rolled directly into CM w/ 9.0.
