[c-nsp] Video in VDI environment best practices?

Unfortunately, we have never seen video over vdi work well. 
Typical BW savers such as Wan opt stream splitting and multicast do not apply to the vdi streams.   
Our tests using Thin clients showed the video bw needed per steam was much higher when viewed via vdi.
End user experience was spotty.  

Our platform was wyse thin clients using either tcp based rdp or their proprietary udp protocol. 

Pcoip may have some VMware features for video.  I'm told Citrix had some way to support it as well.  

Pls keep us posted with any success or other stories.
