What you need is a good chain tensioner design. Depending on what size chain you use (#25 or #35) will dictate how good your tensioner needs to be. Generally 35 chain is more forgiving if you have some slack, 25 is less so.

If you still want to move away from chain, AndyMark has a product they're working on that doesn't require chain. It may give you some ideas.
