I would go so far as to say that at the end of the day, the model for the service that Mega is providing may rank up there in importance with Zimmerman's PGP work, and he Kim (and his minions) just may have the muscle, money, and smarts to make it stick.
Actually, a guy just recently linked this
http://news.ycombinator.com/item?id=5084261 in the reddit thread about us (or rather, he linked to his reddit thread with this link, but you get what I mean)...
...from the looks of it, Mega's encryption seems to provide far less data privacy assurance than people seem to think (and I
kind of understand Kim here, Dropbox-like convergent encryption, and thus deduplication, saves a lot of money and pain, and who cares if it provides the means for preemptive screening of uploaded data and could potentially enable various shenanigans by third parties who
already have file plaintexts and would like to know which accounts are involved with storing those files...)
I was a little careful to use the terminology 'model for' because I've not reviewed the Mega implementation in detail (or more accurately, not read the critiques of qualified persons which I am not.) What I meant by this terminology is that the service provider will not be,
because they cannot be, scanning through and cataloging one's personal data and more importantly it will provide some limitation on how practical that is for governments as well.
I actually doubt the Alice/Bob [abc]/[cde] example in the aforementioned thread is valid in Mega's initial implementation, and even if it is it should be easy enough to rectify if there is demand.
I might point out that
I may be a bit unusual in that I don't give two shits about music or movies so traditional IP and pirating issues are secondary to me. The only vid stuff I care at all about is porn and there is so much of that kicking around which is not encumbered that that is not really a big problem. I make significant use of cloud storage for many other types of documents, drawings, lists, etc. While these are (currently) of a completely benign nature I still do not want any aspect of my existence to be housed in any data warehouse and gone through by anybody for any reason. It's more philosophical than anything else.
