   Shortest TCP session?

   Someone in another newsgroup is trying to get especially high TCP   
   connection setup/teardown rates, which reminded me that I forgot   
   how short a TCP connection can be?   
      
   Can you add data to the SYN, SYN+ACK, and ACK packets   
   of the three-way handshake?   
      
   Can you add FIN on the last (and first) data packet?   
      
   That is, does:   
      
   1)  SYN+data+FIN   
   2)  SYN+ACK+data+FIN   
   3)  ACK   
      
   work?   
      
   Usually, I would choose UDP in this case, but some might   
   like TCP better.
