One other thing - you mentioned wanting to move audio channels in real time - you can move up to 32 channels around in the speaker space, using a client-server program called Immergo. The server runs on the Mac and the client on the Mac or a remote tablet - its web browser based, so you type in a URL. You successively select tracks and move them around a representation of your speaker space. You can record and play back the movements. The movements are realized via mixer matrices in the speakers.
So its two different approaches you can use - pre-prepared channels with movement incorporated (guess you would use the terminology ‘bed channels’) or channels that can be moved via the mixer matrices (object audio style), where metadata containing time stamped 3D coords is recorded.
