Pipe may soon become the Dropbox of Facebook, since it will soon allow Facebook users to file share. The app, set to be unveiled a the London Web Summit later this week, allows users to send up to 1 GB files to other users through a classical drag-and-drop action. When a user sends a file to one of his friends through Pipe, the friend receives a Facebook chat message that prompts him to install the Pipe app and follow the video instructions in order to get the file transferred. Pipe uses Adobe’s Real Time Media Protocol Flow (RTMFP) communication protocol, which was not designed for file-sharing, but for letting Flash or AIR apps communicate with another.

The Real-Time Media Flow Protocol (RTMFP) is a communication protocol from Adobe that enables direct end user to end user peering communication between multiple instances of the Adobe® Flash® Player client and applications built using the Adobe AIR® framework for the delivery of rich, live, real-time communication.

In a digital world obsessed with sharing, Pipe is an app that Facebook users might enjoy. Facebook benefits from users spending even more time on the site. Plus, it is expected that Facebook would avoid copyright infringement since the file-sharing wouldn't involve their servers.
