Actually, it looks like 1078 (TCPMUX) basically runs everything over a 
connection to TCP port 1, so instead of limiting the connections to a 
given service from a single source IP address, you'd be limiting the 
connections to all multiplexed services, together, from a single source 
IP address.  ("Sorry, you can't telnet in, you've got too many IMAP 
sessions open.")

Now, if you ran TCPMUX on all 64K ports....
