"Does not play nice" really means it was designed to run in a non-distributed mode. There has been no work done to verify that it does work in cloud mode, I fully expect some "interesting" problems in that mode. If/when we get to it that is.
About replication: I haven't heard of any problems, but I also haven't heard of it working in that environment. I expect that it'll only try to replicate when it's loaded, so that might be interesting....
