One fly in the ointment that I've encountered is that what you probably want is the Mail clipping service, not the Mail processing that you can do with the funny subject line or funny address. The clipping service gets you the link to the original email, attachments, etc. and the other fails with a message that has just about any sort of formatting. I wonder if it would be possible to set up a Mail rule that ran an Applescript that invoked the clipping service on the current message? You'd have to have the clipping service set to send items directly to the Inbox, not the Quick Entry box, of course!

Out of curiosity, if this all worked the way you want, how many emails/day do you think you would be running through OmniFocus? I find it a bit more efficient to make the 2-minute rule be more like the 5-minute rule when handling email, and skip the trip through OmniFocus.
