Postcode and address validation...?

Hi everyone,

We have a customer who requires a tool to validate addresses and postcodes in Sugar. Ideally, they need a solution whereby users can enter a house number and postcode, and the system finds all the addresses which match this combination. Many websites use this functionality, whereby you can search for your address using these two pieces of data.

I have looked through the Sugar Exchange, but cannot see anything which would provide this functionality (rather surprisingly!). Has anyone out there done something like this, or know of anyone who has?

I look forward to hearing from you!
