Even infinite bandwidth does not guaranee low latency, however these 
guys seemed to run into less problems. I can't really say I tested it in 
the sense of actual results, so be it.

I still uphold there is an impedance mismatch that is mostly by design. 
In X11, server and client are coupled much tighter than in web scenarios 
(resource- and timingwise). This leads to much reduced control over 
client/server task balancing for a given app, plus increased latency 

That's not to say there are no scenarios thinkable which could benefit.

Well it is related but can not be seen as a successor. Seems I fell 
victim to some overstatement.
