If you terminate audio in a central location, you are fairly free as to what to route to it. With regards to inline volume controls, I am sure your clow voltage contractor will love to sell you those. I would NOT utilize them, but would work with stuff that works by controlling LinuxMCE, i.e. Z-Wave buttons, Orbiters, KNX Buttons what ever. Way more flexibility, and you can control the volume for any room in the house *from any room in the house*. And you do so by controlling it at the amp which is located centrally, and not by some potentiometer
If you terminate everything centrally, you decide what sound goes where. You can have your TV sound come out in your living room, as well as on your patio. And can control everything with the Orbiter.
If you use those analog controls your contractor wants you to install, you loose all that.
Do you need a MD in each room? Not really. Depending on the length of your cable runs to your central location, you can have a few MDs in the central location, which feed HDMI over the amp runs to your TV sets and audio outputs to all the rooms.
I've setup my home to have a MD near the place where my video display is. And would add another MD at each other location where I would want a video display. I use squeezeboxes (or rpi's with the corresponding image) in locations where I want audio only. And I have the amps near the MDs / squeezeboxes. I use Denon amps exclusively as they are quite inexpensive used, and are easily controllable via RS232 from the MDs.
If I were you, I would see if you can find some of the LinuxMCE maindevs local to your site, and get him to make a plan on what you need, what you can do, what you can't do. Might cost a grand or two, but will make sure, that you have everything you need.
PS: I am in Germany, so probably not near you. I would do it for expenses paid though, if you could wait til mid of July (13th to be exact).
