Pogoplug only sees and serves data stored on USB drives attached to it. The advantage is you can access it from anywhere, local or remote. If you want to serve files outside your home, the pogoplug does that well and sort of acts like a firewall between your local computer and outside web access. You can copy files from your local computer to the pogo connected drives with the desktop active copy application. However, you would need duplicate external hard disks for the pogoplug.

If you want to serve media only from your computer direct to outside browsers, there is an application called media hive that can do it. I think it's only a media streamer though, where all types of files can be accessed, moved, and copied, and selectively shared by pogoplug, and not just played or viewed.
