Because of this it is possible to use any Shimano 9-speed rear shifter with an 8-speed Dura-Ace rear derailleur to shift any 8-speed Shimano cassette. http://www.ctc.org.uk/DesktopDefault.aspx?TabID=3946
I don't think so. Shimano 8, 9, and 10 are all compatible shifter/derailleur mech EXCEPT for DA8. So you could use any Shimano 9-speed shifter with any 8-speed cassette exDA.
