Mark,
Congrats on the pre launch of your new server. By now you are aware that FSHost only works in the Windows arena.
One idea that might be useful is to 'intern' with an already existing FSHost server. See what they are doing, and learn first hand how they set up.
There are manyFSHost servers out there, and I am sure a few of them would be tickled to have some spirited help, in exchange for learning the ropes.
