HeavyMail is a new company. They have a piece of software that allows you to send large files, and folders over the internet. From a user’s standpoint it works just like email. You create a new message, attach files and folders, address it and hit send. The recipient receives it in their HeavyMail client app. Yes, you can transfer files and folders via ftp, but this is meant for the “average” user… one already familiar with using email. I think it’s a pretty cool service.
They are in beta right now, but you should check them out.
