Hi all -
I (finally) stumbled across a VMware View (PCoIP enabled) linux client. You can download it here:
It's from HP's site and is part of their T5545 update. I downloaded the executable and extracted it to a temp folder and then SSH'd over the vmware-view-client_4.0.0-215529_i386.deb to my custom Debian build and installed it. Then I PXE booted the new image and see that it in fact has the PCoIP and multi-head components (bonus!).
Hope this helps everyone. Not sure why this wasn't available in the first place as competitors are more than happy to hand out their connection clients.
Warmest regards,
--Adam
