These are some intriguing thoughts. The 25.1 release cycle may last a while,
so this could still land in a few weeks (beyond the freeze), out of respect
for your efforts to do this right. If it gets too late, though, it would be
better in 25.2 (which I'm hoping will follow just a few months later).

Would you be available via Firefox Hello some evening, so that you could share
you screen and give me a demo? I'd like to get a better feel for this than my
imagination. I'm available right now in fact. :)
