Chaum ecash is one way to solve it. You'd use chaum ecash tokens backed by bitcoin by an issuer. You would then use the tokens, since they are instant, have no transaction cost and can be anonymous. The ecash tokens themselves require a central issuer that is trustable to avoid double spending, which is it's central issue with it. To side step the trust issue, the issuers would be a large multi sig bitcoin pool. The two technologies compliment each other. Bitcoin creates a purely virtual good that has scarcity and solves the trust issue. Chaum ecash solves the cost, speed and anonymity issue for bitcoin. Bitcoin will become something like the international wire transfer mechanism. One implementation of chaum ecash is open-transactions, i suggest you check it out: http://opentransactions.org http://opentransactions.org
