I got the idea after playing with some WAP sites, that it would be possible to write some sort of API to online banking websites. I wanted myself to have the ability to get an SMS or Email with my Bank Account and balances. This was spawned properly after a night of investigating Westpac's Online Banking system and has gone from there.
One page links to OnlineBankingAPI:
