seeing this question:
Are there webapps that do this more targeted at enterprise?
Ie. I'm looking for a cloud based solution that mounts a network drive in Windows so it's nice and transparent for users, but actually stores files in the cloud, and is suitable for fast access from multiple sites across the globe. So a bit more involved than Dropbox, and not necessarily anything stored locally; just a very fast accessible file-server with good security. Supporting 40+ people connecting and downloading/uploading large files.
