Honestly I wouldn't know.
Just a wild guess. I think there shouldn't be a problem.
Just fire the game up trough you're account and access the beta trough the ODST Menu.
Same way around for you're bothers account.
Halo 3 beta could be fired up trough the Crackdown game. I believe it didn't matter which account would start it up. it just required the host disc (ODST in this case, and crackdown in Halo 3's case)
