A notification just sent out by the official app for Facebook’s F8 conference
later today reads “The Garage and Demo areas are now open! Just
revealed: Parse for IoT, Messenger as a Platform, and the Teleportation
Station.”The alert seems to indicate that Facebook will reveal a version of its mobile app building suite Parse for “Internet Of Things” devices. It also appears to confirm my scoop from last week that Facebook will announce a Messenger platform at F8.

As for “The Teleportation Station”, that’s a bit of a mystery. One guess is that it’s related to Facebook’s vaguely named “Innovation Lab” it created to test mobile apps in simulation of different network conditions around the world.
We’ll have more analysis soon.
