Gravatar picture syncing for Addressbook
It would be awesome if you could support periodic syncing of profile pictures for the Addressbook from Gravatar.
The only issue I can see is which picture would you use if it's synced from Gravatar and then the user changes the picture of the contact on their phone and then it get's changed on Gravatar again? Maybe only sync profile pictures from Gravatar on contacts which have no pictures? Or just last update wins, always.
This is definitely interesting, we’ll have to investigate if the Gravatar terms actually allow us to do that though.
