In the shared variable properties box, specifically with regard to a the target being an rt target, when enabling aliasing, what is the difference between binding to a project variable vs. to a psp url?

The difference is in the type of variable you are binding it to.  A project variable is a variable that lives within the specific project in which it was created.  A PSP URL is an address using the Publish-Subscribe Protocol (PSP).  You can learn more about PSP URLs here: https://www.ni.com/docs/en-US/bundle/labview/page/sharing-live-data-programmatically.html#d28390e65

PSP URLs will enable it to communicate between different machines and also between projects which may or may not be open.  The project variable will exist within the project.
