Using some info from this discussion and other information from Kerio and Maxum I was able to set up all FileMaker Server, Kerio Connect, and Maxum Rumpus all on a Mavericks server while letting OS X Server.app Web, Wiki, Profile Manager and VPN still do their thing properly.
I wrote up a brief but illustrated tutorial that comes with some customizable example files and posted it to the Tutorials section of the RAIS page: http://rais.precursor.ca
