With a bit of tinkering, you could set up a perspective that shows the desired subset you want mailed to you, and an Applescript that "prints" the contents of that perspective to an email addressed to you. Then set up a repeating action in iCal with the script as the alert action.

Personally, I would just have iCal open the perspective at the target time; the perspectives are stored in Library/Application Support/OmniFocus/Perspectives in your home directory, and double-clicking on one (or having iCal do it) will pop up a new OmniFocus window in that perspective, even launching the application first if necessary.
