This is a fairly hot topic and we have been trying to approach it in different ways. Facebook is just one network... there's also Twitter, LinkedIn, regional networks, etc. Ideally, you'd want some way to allow people to download their data from those network and import it to your site, with some level of control in selecting what to upload and what not to upload. It has to be be fully controlled by user. So, there's has to be some mediator that allows to easily download the data, normalise it into readable API/format and allow us to import with approval. We have been in contact with digi.me - a service that does just that, and so far we're at the stage where we need to "match" as much FB/Twiiter/LI/etc functionality as possible to be able to accept that data. Configuration of ONLINE.ME is part of that journey, but I would expect at least 12-18 month until it becomes a reality.
