Bitcoin -> prepaid VISA/Mastercard service (2014 edition)?
There is not a single available solution to go to a general VISA/MC/AMEX card in the US today. Money Transmitter laws (and a host of other regulations) make this a very difficult proposition at the moment.

Some other countries don't have the same issues today, like Canada http://paymentweek.com/2013-11-4-canada-introduces-bitcoin-debit-card-services-238461/ but these solutions are also still in development.
