Re: How many of you will stay at V7R5 lower due to SDA removal ?

Render? I think centralizing that part is almost impossible.

By render I don't strict mean 3d or illumination/texture (we are in ERP context), but also simply rasterize (project to pixel plane) some 3d vectorial definition.
Regarding 3D and more advanced things, totally possible, and I've used those even ten years ago, in remote workstations (even more workstation per chassis, some with dedicated GPU some shared concepts).
I mean, things like watching a movie in a window and running a 3d modelling program.
Was done via PCoIP protocol in hardware (both in client (was just a Samsung monitor with the protocol chip) and in terminal host with dedicated card).
Nowadays (I'm not current nor used recently) the concept is even more refined and even mainstream, i.e. PCoIP is used so stream pixels from Amazon AWS remote virtual desktop to beam the desktop computer to a local thin client.Regarding more advanced usage (3d modelling), nowadays single GPU can be partitioned in multiple GPU and shared using a single host.
For ERP use of basic office productivity just scratch the surface of those systems.
A "just pixel" protocol provides clearly a maximum flexibility... with DDS 2.0 ;-P want to istantiate a canvas with inside a html/js engine ? done. Image? done. 5250? done...
