It's fast becoming the standard with cloud storage and is usually automated in a ftp client married with open PGP/GPG, but ya for barebones services its probably overkill... until a problem ocurrs. My thinking is the problems it actually can prevent or even solve. Like DCMA or State/Gov con concerns, or those pesky NSA letters you cant divulge the existance of under penalty of prison and fines, hacking, theft, and even nosy or criminal data center employees ... not to mention plausuble deniability and no one can open the file but the uploader.
We will look into integrating it with the service, It will take time though.
