Gmail File Space

While looking through the latest issue of Macworld, I ran across a mention of a extension for Firefox called Gmail File Space, or Gspace. It allows you to use your Gmail account to store files through a very convenient, FTP-like interface from within Firefox. Since Gmail is a free service and how it works is subject to change at Google's whim, I don't think I'd use it for either email or file storage for mission critical stuff, but this could sure come in handy.

Here's a screenshot of it on my iBook (I didn't see anything about Gspace being Mac-only, so it should work on other platforms):
