(sigh) Yeah, that's true.

A thought I had, while not an ideal implementation, is if you had an old desktop computer with extra hard drive bays, it wouldn't be terribly difficult to set up your own NAS. I think Windows Home Server even makes it stupid simple to set up (maybe even with a RAID setup), as well as to be somewhat accessible from the web. Unfortunately, I don't think the Windows Home Server setup has the potential to be as feature complete as the rest (lack of Time Machine backups, may or may not provide UPnP local network file streaming... and it's Windows).
