Okay, but why would you? What's the advantage of that? VSTs are resource hogs (when you have like 10+ running at once), not DAWs.

I somehow doubt a full-blown browser connected to more than a couple of VSTs would be less of a resource hog than doing the same in a DAW. On your computer. That you own. In your house. Without like additional 50ms of latency for the data to travel to the server and back.
