I've been working on a Xendesktop 7.6 project, which consists on two flexcast models. Static with PvD and Pooled random desktops. The client wanted a solution that could be used to convert their existing workstations into Thin Client devices--capable of connecting directly to a Hosted VDI desktop. We tested IGEL UDC2 and were impressed with how it worked. There were some initial tweaks, but in general this is a very good solution. The UMS console can be used to easily deploy thin client settings to the UDC2 devices, but also, any IGEL thin client devices.
