from a cursory look at the 'net, it seems like Campy 9 & 10 speed cassettes would be interchangeable (ie, use the same hub...maybe even the same for 11?)...is this correct?

I have a full 10 speed record group I am thinking of upgrading the 9 speed Veloce/Mirage/Daytona group on one of my bikes but I will only do it any time soon if I can use the wheelset & freehub that is on the bike now as a 9 speed. (ultimately doesn't matter 'cause the mixed group will be going back on something sooner or later so I'll need another wheel at some point in the future)

thanks in advance for indulging this basic question!

Yes, you can use current campy hub for both 9 spd and 10spd cassettes. Some hubs (eg White Industries H2) work with 9 and 10 speed only but not 11 speed.

Right.

Also note that first generation (Chorus and Record from 1997/1998, everything else through 1999) 9 speed freehubs have a 26mm threaded lock ring (CS-201 12T+ first cog, CS-301 for 11T) versus 27mm for later hubs (Anything with an over-sized aluminum axle or cartridge bearings - CS-401 12T+ first cog, CS-501).

The 11T lock ring included with a 10s cassette won't mate to one of the older hubs and you'd need to find the appropriate part on E-bay.
