weston is not the only wayland compositor. is the the sample/test compositor.
wayalnd does not mean sticking to just what weston does.
i suspect weston's rdp back-end forces a sw gl stack because it's easier to be
driver agnostic and run everywhere and as you have to read-back pixel data for
transmitting over rdp... why bother with the complexity of actual driver setup
and hw device permissions etc...
what pekka is saying that it's kind of YOUR job then to make a headless
compositor (base it on weston code or write your own entirely from scratch
etc.), and this headless compositor does return a hw egl context to clients. it
can transport data to the other server via vnc. rdp or any other method
you like. your headless compositor will get new drm buffers from client when
they display (having rendered using the local gpu) and then transfer tot he
other end. the other end can be a vnc or rdp viewer or a custom app your wrote
for your protocol etc. ... but what you want is perfectly doable with
wayland... but it's kind of your job to do it. that is what virtual-gl would
be. a local headless wayland compositor (for wayland mode) with some kind of
display front end on the other end.
