Was looking for something similar, couldn't find a thing that worked well, so I had to build it myself.
Too bad I don't have enough time to polish it, but it still works well for me.
Thanks, I was looking for something like this. Alt-C only supports android and windows, and will never support my desktop systems(GNU/Linux and OpenBSD). Thanks :)
EDIT: If it's open source, though, where is the code?
I had submitted my similar open source app a long time back - http://oneclipboard.crushingboredom.com/. Sorry for the shameless plug :)
