Actually you can encrypt it once with everyone's key. I'm not sure internally how that works. But, I know that it does. Just like you can send e-mails to multiple people which all can read.
I guess it just encrypts the one symmetric cypher with all the asymmetric ones.
I'd guess that too, but the explanation that I like better is that it sends the file into deep space and then encrypts the coordinates to each user. Then you pick it up on SETI@...21... Think, that'd reduce the file size also! :)
