Taggedfrog does something very similar on Windows, except it uses a drag and drop GUI instead of the shell. You can have ready made customized tag clusters (so you don't have to type the tags for each file), and it will tag anything, including web URLs.
That said, I would like to be able to tag and recall from the command line in order to integrate tags with other tools. Windows already offers a limited tagging service for Office documents.
