Does broadcast *server* mode still exist?

The delay/replay problem is fatal, at least with a simple public key system 
like I proposed.

There is probably something like a FAQ entry that explains that if you want to 
get time relevant data from A to B, you have to start by sending something 
from B to A, a nonce if nothing else.

You could eliminate duplicates by having the sender include a sequence number. 
 You would have to add a dance to get started.

I don't see how to protect against delays without sending something from B to 
A -- or knowing the time.

I removed the state machine after we had removed enough stuff (like broadcast 
and peers) so that the remaining cases were simple enough to understand.  That 
was a while ago.
