Online storage as hard drive app.

For the file storage feature to be completely killer, it needs to interface with multiple platforms in a seamless and easy to use way.

If you developed a program that would make the filestorage on GMX show up as a hard drive under mac and windows so that files could be dragged to and from online storage, it would be awesome. GMX users could download this program and then use it as an easy way to share files with others (after creating public and private folders, etc.)

Also, an iPhone/android app to access these files would be nice too (since not all smartphones support downloads directly off a web interface)
