Honestly, I think the most reasonable choice would be to just release it to smartphones and UMPCs that have touchscreens. It not like the sound quality would be massively (if at all) worse (for Christ's sake, we're not talking about the N-Gage here, people) than it would be on, say, PC or CS.
I can see this being heaps fun on an iPhone/iPod touch.
