9spd brifter and 8spd cassette
Would it work? Is there a way to lock out the last shift click? Or it is just stupid talk?
That works with a 7400 series DA RD or any other shimano derailleur using the alternate cable attachment. http://sheldonbrown.com/dura-ace.html
Will generally not work, too much difference in spacing.

Incorrect, read the link above, it works on my bike and many others.

Shimano 9 has a sprocket pitch of 4.35 mm, Shimano 8 has 4.80 mm. Campy 8 has 5.00 mm and Campy 9 has 4.55 mm. Too much difference for decent performance in stock configuration.
