I'm keen to get some advice from others before I jump in and spend money. 

I have been using a Squeezebox Duet and a Netgear ReadyNAS to stream my audio to my A\V Receiver and then a A C Ryan PlayOn HD to play movies.

I particularly like being able to control the SqueezeBox player via my Android phone or a web browser but haven't multiple boxes, remotes etc doesn't have much WAF.

I'd like to integrate the functionality of these into one box and was thinking of building a PC with XMBC on it plus a Squeezebox player and then being able to control the audio via the Android phone so the TV doesn't have to be on.

Any thoughts \ opinions on software and perhaps IP\IR Blaster etc to replicate this?
