I use Ogremax 2.2.7 for exporting (you must install plugin for ogre 1.6.x)
and for importing i don't know any oficial importer, but i know one that works the 25% of the time (well, 25% it not so much but worked with some FH models)
i made a tutorial for importing (the tutorial was deleted, was my first post here)
I found a script for importing and worked for some meshes of FH
ImportOgreXml.msbut didn't work for canine and feline body model, so i modified the script to this.
ImportOgreXmlbody.ms PD: you know how to import zootycoon2 meshes?
