So the only value of cross-signing keys is to increase trust (of the public key). IE: If Alice and Bill signed Cindy's key, and I receive something from Cindy it must be Cindy (not somebody protending to bre Cindy) becase I know Alice and Bill and trust them...

(But Cindy also needs to give you her cross signed public key by Alice and Bill
 right?)

Ahh, OK, I thought cross signing might mitigate that - but then you confirmed my doubts, tks.
