Off-line browser-based terp?

I’m working on a fairly simple IF (using Inform 7), and planning on generating Z-code. I know that if I’m on-line, I can play it on any computer in any recent browser using Parchment - but I’m thinking of handing this out on a thumb drive at a con, and I’d rather not force the user to install a terp on their computer, or to be on-line to play it. Can Parchment be loaded onto a thumbdrive and run therefrom, invoking the user’s default browser? Is there an alternative to Parchment that can? Am I asking for something that doesn’t exist yet?

Parchment works perfectly well offline (and from a thumbdrive)! :slight_smile:
