I've used 10 speed road derailleurs to shift 9 speed drivetrains and also used 9 speed mountain on 10 speed road drivetrains. The latest version of 10 speed Tiagra is not the old SIS standard (1:1.7) so they aren't backward compatible with 9 speed and less. I wish shimano would have used the dynasys cable pull on all the 10 speed road stuff, it was so nice to be able to mix and match mountain cassettes with road gearing. It's still possible but it's more work now.
I'm glad I don't have any reason to visit uptown regularly, cycling there doesn't seem any easier than before they built the lanes with cars being parked in them haphazardly.
