we do remote coding mostly for the pairing and code reviews. two or more people connect to same server, first tmux (or screen, which we used in the past) and vim from inside tmux for editing.

to integrate Facebook and and PayPal remote coding usually not required, it is simple to configure a dyndns account and a port forwarding on the router to continue to work on your own local development machine. Any hassle of configuration pays off pretty fast due to increased pase of development and lower overhead.
