Along these lines, I want to know what the catch is. Where/how are the files stored, how do they stop us from going past 2gb, is there anything in place for when the RIAA/MPAA come calling? More critical replies please, YC.
That's not Dropbox, that's the Nautilus integration. That is, you keep the essential parts proprietary and closed, and open the parts where you hope others to do work for you. It's not the oddest strategy, but it doesn't live up to the promise either.
On the other hand, if you freed the daemon too, you could get included in Linux distributions, and people would know what all Dropbox is doing on their computers.
It's here, it's open source, and it's free software! Dropbox for Linux is finally available and ready for your everyday use.
Further down the page:
-- dropboxd is a per-user closed-source daemon process that makes sure your $HOME/Dropbox directory is properly synchronized.
