"sim" --> "mobsim", e.g. SimEngine --> MobsimEngine
"Q" --> "Net(sim)", e.g. QLink --> NetsimLink
The idea is that the "q" mechanics remains inside the "netsimengine" (to be renamed into qsimengine), and what is exposed is just a netsim interface.
This is in conjunction with attempts to pull the 2dsim by gregor underneath the umbrella of the qsim.
