<antrik> Wayland should be very portable. all the system dependencies are
  in the infrastructure, such as DRI
<antrik> we have had a DRI task (for X.Org) for years
<antrik> (in fact I would be the right person to implement this,
  considering my background -- by quite frankly, I doubt I'll ever do it)

<youlysses> Is wayland something that will be semi-easy to port to the
  hurd? I saw GNOME is heading in this direction.
<pinotree> wayland at the moment is linux only
<tschwinge> youlysses: A DRI implementation will be needed.
<pinotree> that, and libdrm compiling
<youlysses> So it will take some work ... but theres no *HUGE* design
  decison that would inhibit it?
<pinotree> i know it uses epoll, for instance
<tschwinge> youlysses: I cannot judge how complex a DRI system is, and how
  much needs to be designed vs. implemented.
