I think the main problem with the the Internet at the moment is that people have to register on every site they visit. I agree with what you say that you need to only ask someones' information once.
People who do a lot of online shopping or access forums have their personal details scattered across the Internet. For the individual it becomes a nightmare to keep that data up-to-date and for the company it is a nightmare managing that data (they never know whether the data is up to date).
I work for a company that has a unique service where people can manage their personal detail securely. Sure, you might ask how can we trust them. Well, do you trust all the companies you provide your personal information to? The fact is, if you want to purchas something online, you need to provide your personal information.
They have developed a web service that integrates with just about any application allowing businesses to get up-to-date information from their database. If the customer move home, he only need to update the information in one place and the business can request an data update and instantly have all the up-to-date information.
This makes data capture much easier as well as you only need a few pieces of information from the person visiting your site and you can request the rest from the central database. People might be less reluctant to provide information as it does't take time and they authorise you to use their data and also know that they can request the data to be removed.
I thought this service might interest you and provide you with an alternative way of capturing data online. The company is called iamdentity (www.iamdentity.com).
