If only this was real
If everybody had Gigabit Internet and IPv6 we could do away with all of these clumsy personal "cloud" solutions. You think Amazon/Box/Google/Apple/Microsoft storage is too expensive for remote backups? Tired of swapping files around on sharing services to get your vacation pictures to Mom? Your NAS, if recent, already has remote backup syncing to another NAS. You probably already have at least 1 low power device that can securely share any number of files over the Internet at 600+Mbps. Nobody has it turned on because it's slow (Basic AT&T is 768Kbps down/384Kbps up), complicated (need to buy IPv4 addresses from idiot tech support), expensive (must buy "business" upgrades), and likely prohibited (servers and caps) with ISPs like AT&T.
AT&T's U-verse is the most underwhelming hardware upgrade that I've ever seen. It's designed to be nothing more than a viable downgrade for people who've been screwed by Comcast. There's no way that AT&T will produce a viable Gbps product to consumers.
