Hey there, I could certainly get you linux binaries if you agree to be my linux beta tester :). The issue with tray icon is that it's pretty critical to application's existence, in that the app needs to stay in the background as long as the computer is open. It's a daemon, essentially. Without a functioning tray icon, it's impossible to shut down the application other than via kill [pid] or another way via shell. If you are interested, please email me (in my HN profile). I'm definitely interested in maintaining Linux binaries or help people maintain them.
