I'm going to try rewriting the whole application in Python starting next week but it will probably take a while because I'm not so good at Python. If it can be done though it would run on all operating systems instead of just OS X making it a lot nicer!
I'll also look into how to automate file system mounting over SSH or VPN to create a mini file server that can be accessed away from home. This could be helpful for moving large files (like HD movies) from a laptop that's away from home to a server on your home network. Just mount the home server on the laptop, drop the files you want to send using your normal GUI (like Finder, Gnome, or whatever), wait a minute, then disconnect. It's kind of like FTP but hopefully faster and easier to use.
If I get all that done I may look into packaging it into the main repository.
