Thanks for the thought, dianne, but, in short... No.
I'll go the two-extension route just so I can upgrade to Snow Leopard, but I won't be happy having to take two actions to accomplish the same thing formerly accomplished by one (although I'll enjoy the added functionality the combination of the two extensions will deliver...if I actually remember to use it).
(I haven't got a multi-function trackpad, but even if I had one I'd go the control-click route, anyhow.)
