As the space matures I'd love to see a company that offers double spend insurance for a given tx.
For example changes could wait for 10 minutes worth of blocks then request a quote for double spend insurance. The company evaluates the probability of a double spend and maybe even has a couple standing contracts with rentable hashing power to be able to target smaller PoW chains and prevent any double spend attack.
There are lots of interesting and cool problems to be solved in evaluating the safety of a given tx. Unfortunately I don't know if the space is mature enough that exchanges would actually use the service.
