RAC is not free, that's exactly the point Kellyn was making. If you want to use RAC under your EM repository, that's an add-on, paid option.

RAC free for OEM - new one on me (although we do have site licenses so have had no need to investigate to a great detail)

Since without EM, we DBA's are often in the dark, I appreciate the proposal of RAC for the environment, but doesn't this kill the free licensing option that many companies take advantage of to keep costs down? I would prefer to use my EM monitoring and alert script vs. having to go to my manager and explain to him that I need more budget for licensing costs! Correct me if RAC is free for EM, but I see no documentation saying otherwise.

Take a look at this:
From your description it sounds like you are only planning a level 1 setup (1 repository instance and 1 OMS instance). If that is the case, I see very little benefit to having it on 2 machines, as opposed to 1. If either DB or OMS machine dies it's all gone anyway. Since the two servers in this setup provide no additional resilience, I would prefer a simpler solution of a single server myself.
Of course, if the plan is to move to a more resilient solution in the future, it may alter my opinion somewhat.

I now have new clients, new systems to work on and at least two EM12c environments to build out in the near future.
