This doesn't contribute to the conversation ... without further elaboration on what your point is, I'm assuming that you're pointing out that my question is analogous to previous (good to ask!) questions about market and user model for an "eventually very big" application.
Not very enlightening: just because Dropbox became big in one environment, doesn't mean the same questions aren't important in new spaces.
So every time someone comes around with a sentence like 'but if I can whittle away at a free and open source version, why should I ever consider paying for this?', the answer will be that Dropbox thread ;-)
