+
+ This class provides an interactive console TCP server.
+
+ \todo Add readline support
+ \todo Add interactivity detection using timeout
+ \idea To support blocking commands, we could give the Client 'suspend()' and 'resume()'
+ members. suspend() would probably throw some kind of exception to transfer control back
+ to the Client instance. on resume(), the command would be called again, maybe setting
+ some flag or something. Example for use: Host name resolution: Here we can just built
+ our own little host-name cache. When the name is not found, we ask the resolver to
+ resolve it and call 'resume' when the name is found. Since it is in the cache now, the
+ command will now complete.
