Sorry about that, the conference was on Feb 2, and it's supposed to be out any day/week now. I don't have a date.

There is a blog-style writeup here: https://fwsgonzo.medium.com/an-update-on-tinykvm-7a38518e57e...

Not as rigorous as the paper, but the gist is there.

Thanks! I'll keep an eye out for the paper.
