I used to use an MX Revolution mouse[1] that had what you describe. Multiple thumb buttons, that amazing flywheel scroll wheel, that other thumb wheel. I loved that mouse. Unfortunately I love trackballs more than mice now, and am severely limited in my choices. The Trackman is nice, and has a couple of extra buttons, but it would be so nice to have something close to what I had with that Revolution mouse. In response to your comment above, no I wasn't being ironic :). I'm sure I've seen similar schemes before that informed my "idea", though.
