It would be great if a montior could be created to test a Citrix or RDP connetion and also some sort of printer test.
Also if its possible to take any of the monitor where its an application test across a network and split out the response time of the network and also the response time of the applications so if your running a telnet monitor it would display the network response and the telnet response as seperate figures, while the single figure gives us an idea what the response time is, if it goes sluggish we can't 100% say its the application or network as we don't know.
