+- remove Nagle algorithm
+	- use TCP_NODELAY
+
+- support multiple client connections at the same time
+	- first client has control
+	- additional clients can see the traffic
+		- read-only: requests from controlling client and responses from tty device
+	- need to avoid unintentional lock up if controlling client stays connected but user goes away and forgets about it
+		- additional clients should be able to force disconnecting controlling client
+		- first additional client that forces this becomes controlling client
+
+- require username when connecting to the server
+	- allows tracking users
+	- makes the feature above (forcing disconnect) easier to use
+		- username can be connected to a person easier than an IP address
