How about encrypting such news with an RSA-Key or so, and just forget the secret key. If anybody cares about the information, he can gather computing powers to factorize the public key, and then can read the public encrypted message. Just hope that computers are not fast enough into break the key in already 10 years :-) (Yes , I know, this is a silly idea:-)) Just for my curiosity: How would you assure the information was stored in an archive,which will be openend in 30 years ? In every good thriller about spies, there are files which are not recorded anywhere .... :-) Second Idea: Assuming the information is reliably put into a kind of achive and the problem lies only there to get people to 'open' the archive after 30 years, make this independent from people. Any kind of physical process wil do: Place a radio-mirror in about 15 Lightyears distance (yes - silly - I know) and just send out the message you want to have publicly available after 30 Years. Or bury it somewhere where erosion will let it get to daylight after 30 years. Put the information in space, and give it a kind of orbit, which with high probability comes back to you after 30 years. In the meantime distance shall be as big as possible :-=) Dont take me too serious ;^) gec -- Instruments register only through things they're designed to register. Space still contains infinite unknowns. Germano Caronni caronni@nessie.cs.id.ethz.ch
