Lately, I have been working on a remote editing plugin for ST2. Currently, it only works on windows, but shouldn't be hard to port for Mac and Linux, which is probably what I will do next.
After installing the plugin and setting up a server, you can use ctrl+alt+shift+(o/s) to open or save a remote file.
You can download it & find out more at https://github.com/stkerr/Sublime-Text-Remote-Editing
Let me know what you think or if you find any bugs!
