That was my first thought as well. There are tons of file sharing services that already exist, but I think their advantage here is allowing people to send files larger than 20GB. Using DropBox, the limit is 20GB or smaller.

I guess MASV is transparent about file sizes (no limit) and bandwidth is the resource you pay for, so there is transparency on the SLA.
