  That last one is probably a good method - it universally works.

  While the client could do some of the work, it (at least the C client) 
currently doesn't watch commands that much.  It watches it to the extent to know 
if it is a command it should execute or a command that it should pass to the 
server, but beyond that, it just passes the data on to the server.

  Since the server currently says 'you ready abc', putting in a note that it has 
components doesn't really add much in the way of extra messages, and seems like 
a pretty easy solution.
