Re: [9front] Thoughts on Wayland?

Yes, plan 9 doesn't support that -- resources can be located anywhere
on the network, which comes with odd implications about failure domains.

With mmap, this is is very difficult to paper over on a single machine;
it gets worse when multiple pieces of hardware are involved.

While it's theoretically possible to do mmap over 9p, it's not going to
be a good experience.
