Email to FTP?

You know what would be awesome? What would be awesome is if someone created an email to FTP service. I'm talking about the kind of system where you could simply email files to your server.

To upload files related to BlogCampaigning, I have to use either an FTP program (using Fetch for Mac right now) or Dreamhosts web-based FTP.

It would be way more simple if I could simply email files to my Dreamhost space. The FTP login information could either be specified in the email body, or set up with an account to which the email is linked. I envision being able to specify the path in the body of the email.

Is there anything like this out there? I've taken a look at YouSendIt, but it isn't exactly what i'm looking for. There could also be a huge flaw with this system that I'm just not seeing.
