I've thought of some non-DRM uses of TCPA/Palladium technology 1. Electronic voting machines (as in Brazil)--that way you can tell that the vote totals that are communicated to you were indeed generated using the authorized software. I still think there should be an auditable paper trail.
2. Prevent cheating in open-source network games. In competition, you could know whether you're competing against the un-modified versions of the software. This problem was noted with Quake: http://slashdot.org/articles/99/12/26/1255258.shtml http://slashdot.org/articles/99/12/27/1127253.shtml Kind of ironic that TCPA could actually solve a problem of open source software.
