I used to use -- past tense -- Vindigo when I first got a Palm M515. But quickly developed a very low opinion of them over come CC billing issues. Experiences similar to this fellow's on here:

CitiCorp -- maybe not long for this life -- has a nice desktop app for their credit cards named "Virtual Account Numbers" that makes the process of using virtual/disposable account numbers almost seamless. I should use it more often.
