Paragon makes some couplers IIRC that can be used to split the rear triangle. Since the belt can't be cut or broken open like a chain, you've gotta be able to open up the frame. I've looked at doing a conversion to belt before, but never had the time/money/courage to do so. You'll need somebody who can cut the frame and weld the connector in with a fair bit of precision. You will lose your gears, but a lot of beach towns are pretty flat from what I've seen, so I suspect that won't be a huge detriment unless you're on an island.
