Are there issues with deploying the Splunk App for Unix and Linux (5.0.3) & Splunk App for Windows Infrastructure (1.1.3) with Splunk 6.3 Search Head Clustering?

I have a distributed non-clustered Splunk Enterprise environment. I am planning to implement Search Head clustering and a multisite indexer cluster. I know that the current Nix and Windows Infra apps haven't been certified yet by Splunk in a SH cluster, and there could be limited support from Splunk in the event of an issue. I am sure there are users that have deployed the Apps in a SH cluster. Are there any caveats that people have seen on the deployment of the current shipping applications in a Splunk 6.3 SH cluster?
