The one thing I have not found a solution to yet is that, when IE9 makes an AJAX call to get more data, I can't send the data in binary form. I have to use Base64 encoding which expands the data and puts more workload on the browser and my server... Actually, I care more about my server and the bandwidth this data expansion will cost, user performance is likely also affected a little.
Still, getting the KVM working in IE for the first time is quite nice! Screen shot below. For people who don't know, this KVM feature comes included with the Mesh agent. Just install and go. As of now, this KVM feature is Microsoft Windows only. Linux and Mac OS just get the command prompt using the terminal feature.
