There is (was) a browser plugin. I imagine an NaCl or PNaCl based version of emu would be the way to do it these days.

Hello

Some while back someone posted a link to an site which loaded what
seemed to be a full instance of Inferno in a browser window.

I thought I'd bookmarked the site, but I didn't or cannot find it now.

Anyone recall the post and link?

Thanks.
