Another way to Bill for E-Mail

Postful is a pretty ingenious service that creates and sends written snail-mail correspondence from e-mails forwarded to the service for just $0.99 each.  This could be a KILLER application for lawyers, especially if confidentiality issues, firm branding and other details could be worked out.  Imagine being able to send real honest-to-God letters from your blackberry, without secretarial help.  Very Cool!
