I was thinking in something , is not quite php related, but I was thinking of an app that would encrypt a file (that file could be anything) and the author would create an encryption key giving an amount of money to be collected. It would become public and anyone could give as much money as wanted. when the needed amount was reached the file would be public to anyone (decrypted). does it make sense? I am calling it "Distributed File Purchase Encryption" (DFPE) ~birdzoom
