And then to switch HDs it would be just like selecting an external HD linked by FW to boot into--just hold "option" key down and the boot selector window will show the available systems . . . . If it doesn't work there is always SuperGRUB2 to use to boot systems . . . .

I'll probably give this a try later this week. If it will work out as you have described, that would be perfect.
