Firefox Send: Private, Encrypted File Sharing
It really is a shame that there still isn't a easy way (A person whose computer knowledge extends to using facebook), that I know of, of sending arbitrarily large files that isn't tethered to a specific cloud service and is also reliable (can tolerate connection dropping).It seems that bitorrent protocols are pretty close, but I don't think there is a seamless client that allows for "magical" point to point transactions.
