Livedrive

www.livedrive.com allows you to save, store and share data over the web.
Once registered you get your drive space URL and can then access and manage the files in much the same way as you would those on your computer's physical hard drive and there is no size limit to how much you can store so on there.

The application works well and fast and that is exactly what you want when you are transferring data back and forth.

If you have video stored on the drive you can stream it directly without having to download it onto your computer first.

This is only free for the duration of the initial 30 days trial period. But if you are thinking of investing in some on-line real estate this is definitely one to check out.
