Fixed it. There is
no problem with using Sram cassettes with Shimano derailers or vice versa. You can't, however, use (most) Sram rear derailers with Shimano shifters...at least not mountain bike ones. They have a different cable pull ratio.
Don't know about Sram road stuff.

I'm 90 percent sure they're the same for 9-speed too - a guy I ride with runs a 9-speed SRAM cassette and a Shimano derailleur, and it's perfectly adjusted.
9-speed and 10-speed (not sure about Dynasys). I've used Sram cassettes with Shimano derailers on 7, 8, 9 and 10 speed systems. There's no problem with the spacing. Sram cassettes shift, in my opinion, better than Shimano.
