You consider porting to be a user subject?

I haven't tested them lately, but I believe the answers should be yes.

I haven't heard.  I'm still not entirely sure what the relationship between
xwayland and different compositors is expected to be.

It may be better to ask the Qt folks.  #qt-labs on irc.freenode.net in
particular.  I'm not sure which mailing list is most appropriate.

They seem appropriate.

Qt apps don't even know which backend they're using, it's all nice and
magical.  And last time I tested, the Qt5 apps worked with the weston
compositor, but the Qt5 demo wayland compositors crashed, but were expected
to work with wayland apps.  I suspect xwayland stuff hasn't been handled
with the Qt compositors.

There's some info here:  http://wayland.freedesktop.org/qt5.html

The build instructions are old, you'll at least need a couple more modules
to build it.  The porting section may be useful to you.  

If you find better info, please report back.
