Assuming you carry them with you in the house, and no one else will need to adjust volume, sure, that will work... Keypads allow a lot of other functionality, but they can be expensive, and there's nothing wrong with a simple system (using local or remote volume controls).
Does this make sense?
Yep. To control with an iTach, note that you'll very likely need the Global Cache GC-to-Xantech compatibility cable (GC-CGX). I need one to make the iTach work with my Aton video matrix.
The amp doesn't have a digital audio input, which is a pity - not sure how much difference this will make given the limitations of in-ceiling speakers.
None whatsoever... Most whole-house systems are analog-input-only, regardless of price.
I will want to be able to play music stored on a hard drive (NAS or computer) and control it from the iPhone. What is the best way of doing this? I have an old XP machine I could use. I was thinking of running iTunes on it and controlling it by the Apple Remote ap. Is this a good way of doing it, or is there something better? I would like to be able to create playlists, play albums (not just tracks), easily browse and locate music. Another idea is to use a single Sonos ZP-90 as the source.
If you're starting from scratch here, definitely look at the Sonos box. Does what you want, and has Internet radio, Pandora, SiriusXM, etc.
I have my music on a 'server' and use iTunes and an Airport Express to stream it to the A/V system, controlled with Apple Remote on an iPod.
Hope that helps. Most important part of any good multi-room system is to ensure you can control it, turn it on/off, etc. from the room you want to have music in. Having to go elsewhere to select tracks, turn the thing on, etc. is a hassle and makes it much less likely to be used on a daily basis.
