Emailing all results as a file attachment?

With Webform, one can of course manually download all captured data in Excel or CSV format.

I'm looking for a way to automate the manual download process by emailing a webform's results (all submissions) as a file attachment to a designated email.

Is this possible with Webform Bonus Pack?
If so, would someone be kind enough to tell me how to go about setting this up?

If not, any suggestions? I don't need anything fancy in the email itself. Plain text will do. The attachment is the important thing.

Many tanks!
