Sorry if this is a duplicate idea I searched and couldn't believe it hasn't been posted.
This idea is to add Linux RT deployment support for desktop PCs. NI in the past has had a process for purchasing an Phar Lap RT license, then deploying it to a normal x86 based PC. Here are the System Requirements, and a manual.
This opened up the door for desktop PCs to become embedded PCs, controlling NI hardware, but allowing for an upgrade path where embedded cDAQ devices, and even PXI controllers don't have many options.
At the moment there are unofficial ways to get Linux RT on an x86 based desktop with limited success, but no support. These options are outlines in the comments of an idea to allow for a VM of the Linux RT environment. NI could go with a similar route to Phar Lap and sell a license with a list of supported hardware.
