Yes, in just a trillion iterations you can test all possible keys. But if for testing *each* key you will have to figure out whether a text /signal you produced represents sensible speech... - it may be prohibitively expensive.

Well, what if you're "close?" Will it sound "kinda sensible?" Perhapse it would sound like long distance.... ;^) Just a thought. +-----------------------+-----------------------------+---------+ | J.
