There's 2 ways we can get to a Brackets running on Linux. The first option is to add a linux target to the new CEF3 based brackets-shell app. We still need the shell app to get native file system access. We've also experimented with running nodejs on the client side and getting file access over WebSockets. Brackets is then hosted on a nodejs HTTP server and run inside of Chrome instead of CEF3. This solution works, but we haven't pushed this much further than a prototype yet.

Do you have a repo with this prototype? I would really like to see this possibility pan out. I think using node to interface with file system is the most feasible and portable at this point.
