There are solutions, like VNC to some UNIX-ish machine, but, yeah, a native browser would be cool! 9front has a hypervisor, you could run something in there. https://man.9front.org/1/vmx
So, something I’m thinking about here is that the 9p vision has always seemed really cool to me: expose all the resources in the network in a unified way that enables the whole network to be used as if it was a single computer. But, since this is a protocol-oriented vision of computing, it enables arbitrary implementers of the protocol to participate “natively”, even if they aren’t actually plan9 systems.
Author here, it's simple to use if you're building simple stuff, it's complicated to use if you're building complicated stuff. Cool thing is, it gives you the flexibility to build complicated things without getting in your way.
"On Unix, I used RCS fairly happily. It was too verbose, but I fixed
that. RCS, like most version control systems, also believed that the
RCS archive or repository was authoritative and I don't accept that, I
think that the checked-out source is authoritative. If you are
grepping source, you really don't want to grep the archive files, and
you shouldn't have to check out source just to compile. I view the
archive as just history. So I added options to do things my way.
For my purposes, the Plan 9 dump, cp, diff and idiff work well. I
don't miss a formal version control system.
Git is a horrific botch of a version control system: wasteful, slow,
stupid, and unpredictable. When I check in source file(s), I want a
snapshot taken always, and I don't want to be told, no, you can't do
that, you have to rebase. The fundamental problem is that companies
want to believe that multiple programmers can edit the same program at
the same time. That's a great way to introduce bugs and break things.
When editing a program, you want to have a stable view of it, so you
know what you can rely on, you don't want it to be shifting underfoot.
The idea that you can apply an arbitrary set of diffs, or subset, to
some version of that program, and get a meaningful and correct program
out is absurdly optimistic; I wouldn't trust it."
