2X the software company recently announced the launch of 2XCCOS CloudClient, a Linux-based operating system that give you access to WebApps, Remote Desktops, ICA & Vmware View.

It's approximately a year old but it's still a great video demo anyway of Brian Madden testing Citrix's ICA protocol, Microsoft's Remote Desktop Protocol and Redhat's SPICE protocol (previously by Qumranet).
