Thanks for the update. I have quite a few questions...

I was under the understanding that Ubuntu 13.10 would still use
regular X by default (like 13.04) and Ubuntu 14.04 LTS would be using
Unity 8 but it sounds like that's not today's plan.

Like Kubuntu we expect to switch to Wayland in the next year or so.
It's nice to see that the various desktop environment can run on XMir
but I'm still not clear on whether there are any benefits to doing so.

How do you expect things to work for users who need proprietary
graphics drivers in Ubuntu 14.04 LTS? Do the existing NVIDIA and ATI
drivers work with XMir yet?

Mir currently requires LightDM, right? Does XMir also require LightDM?
For Ubuntu GNOME's purposes, LightDM so far doesn't provide quite the
integrated experience GDM does (specifically lockscreen and GNOME
theming; and next year, Wayland support).

I think Rebecca Black OS has you beat there. Unless you don't think
Rebecca Black is mainstream enough...

There's a chance that Fedora 20 would be released with Wayland by
default before 14.04 LTS.
