Getting big files to people through e-mail is a problem; most ISPs have size limits on e-mail, and so files bigger than 3-5MB frequently don’t get through. A number of services have popped up to address this issue — companies like YouSendIt and FileCourier provide for safe and secure file transfer. Now Streamload is getting into the act — you can sign up for a free 10GB account (limited to 100MB per month upload/download), which allows you to send a whopping 50-terabyte file with a single e-mail message. Please, please do not send me a 50-terabyte file.
