Nothing about this is a virtual machine. It is an API that exposes a lower-level Audio interface. I don't need to spawn a virtual machine or mess with any DLLs or figure out libraries because I can simply load a browser. Nothing is saying this needs to be on a remote server, it can be a local .html file for all it matters.

But hey some of us still run around with MS-DOS 5.22 on that new Spectre-ridden, rowhammer-ready i7 because DOS/4GW is hella stable.
