the obvious one is about three comments down - a guy in the UK wants to join up and use the engine. I suspect that most mortgage providers would be happy to have you play with a "independent" site that shows you how much richer you will be in 20 years if you buy their mortgage, and price comparison sites would love to show you which mortgage will pay off most in 10 and 20 years.
That's probably worth following up - is there a way of putting multiple mortgage lines in there ? I assume its doable.
This could well be problematic under UK financial regulations. You are giving financial advice, which is a regulated activity and as far as I can see hard to do with automated services under the existing rules, for personalised services like this (and also if you charge). Most financial advice is from journalists who are basically exempt from the rules, or are generic not personalised.
The situation in the US is fairly similar I thought, would be interested in the legal situation there, as I think this type of service is very useful for people.
