Gigashift - File Sharing With a Business Model
Gigashift is a file-sharing service with a twist: your file recipient can begin downloading while you are still uploading the file, all files are encrypted, pause/resume functionality, and the ability to upload a 10 GB file in one upload.
The service uses a simple Java applet which provides pricing once you select the files to upload. Up to 200mb is free, and then the pricing model kicks in.
Gigashift appears to compete directly with other popular file sharing services including YouSendIt and Rapidshare. Gigashift files can be secured with a password and you need the unique id for each file to download it.
