[X3D-Public] DASH-X3D new profile - Interoper abilitypoint

Not sure how you use DASH with x3d. What does it look like?
I had an idea -and may get to it in the next year- for something I call 'Server-Side Rendering' or SSR for short. If you've got beautiful Crete 3D tourist scenery -in X3D format- and want web surfers to be able to go around in 3D -but without heavy-duty x3dom .js, and without plugins- then the idea is that the client swipes/drags a 2D Html5 canvas which causes a 3D grid of construction lines to be redrawn as if navigating through the grid in 3D. When they lift their finger/mouse button at the end of the swipe/drag, the cumulative navigation is sent to the server, which moves the avatar in the scene and renders the snapshot from the new viewpoint pose, and ajaxes the view back to the client.
This would need an x3d renderer capable of holding session state -if the scene state is different for each user- or else passing back the cumulative navigation in a cookie or restful url after correcting for collision and gravity to the cumulative navigation.
Perhaps DASH-X3D is something like that, except the client has no control over the path, and instead of ajaxing snapshots a movie-like MPEG stream is sent.
