I'm close to a beta release for Locatable, and I'm excited enough about it that I wanted to give a quick preview, from a tech-centric point of view. Locatable is an application and geolocation federation service that let you share your location (GPS coordinates, or any decent facsimile thereof) from your iPhone or iPod Touch to any web site, via the built-in Safari browser. It takes advantage of the new client-side storage capabilities of Safari to allow some very nice anonymity and privacy features -- notably, the user's location is never stored on the server side, with the service at lbs.tralfamadore.com acting as a gateway to storage on the device. There's a lot to say about this and its relationship to similar services such as MyLoki (Skyhook) and FireEagle (Yahoo!). Both of those could be integrated, as can just about any existing location-based service. Anyway, check out the concept and check back for more updates soon.
