Those of more technical inclination should probably start here:What?
The NetVST Project is a collaboration between Shane Dunne in Canada and Hermann Seib in Austria, to develop a way to use Virtual Studio Technology (VST) plugins across fast local-area networks.
How?
A special VST host program called NetVSTHost runs on one computer, called the NetVST server, and the VSTs it loads can be used in a DAW program running on a different computer. This is done by loading special proxy plugins into the DAW, which communicate with the server across the network.
Why?
The first benefit of this approach is that the proxy plugins don't even have to use VST technology; they can be Audio Units (AU) plugins as well. This allows Windows-only VST plugins to be used inside a Mac DAW such as Logic Pro, which only supports AU plugins.
The other major benefit is that, because the actual VST plugin is running on a separate computer, it won't slow down the DAW, no matter how much CPU power or memory it uses. If many CPU-hungry VSTs (e.g. software synthesizers) are needed, one can simply put more NetVST server PCs onto the network.
Does it work?
At this point (March, 2017), the NetVST software is at a very early stage. It works, but just barely. If you are adventurous enough to try it, and quite ready for your DAW to hang or crash sometimes, pop over to the Downloads page on the NetVST wiki and get your own copy. It's free.

I just stumbled upon this, so I know almost nothing about it.
