First off I wanted to say a big congrats on an awesome presentation last night Aaron!
I was thinking about the multiple recipients thing last night and think I still disagree that you can not encrypt messages to multiple people. My reasoning: The crypto used in public key cryptography is really slow right. So instead of encrypting the entire messsage with that algorithm doesn't GPG generate a random key, encrypt your data with a fast symmetric cipher using that key, and then encrypt a copy of that key to the recipient? Same idea as with SSL when it's negotiating a key to use for it's symmetric cipher. So assuming this is true, which I'm fairly sure it is, wouldn't encrypting to multiple recipients just attach one copy of the symmetric key encrypted for each recipient. The message data itself would still only appear once in the GPG output and would be encrypted using the symmetric cipher.
