Yes, we keep a record of the facebook user ID for everyone who adds the Facebook app. When we install the Facebook app in your profile, we use the API to ask for your Facebook friends, which are returned only as a list of IDs. We compare this internally to our record of others' IDs and present those to the user.

Most of our identity matching code is open sourced at http://identity-matcher.goo... although I think the Facebook bit isn't in there as it's more intimately tied in to the rest of the Facebook code.

When Dopplr finds your friends on Facebook, how is it matching FB accounts with Dopplr accounts? Is it limited to people who also installed the Dopplr app? I suppose CrowdVine networks are small enough that we could match on name. Also, do you know of any open source reference implementations? If not, we'll release ours (too late for SG Foo though).
