I don't know how I could translate the objects correctly without 
gemheads or separators, maybe storing the current XYZlocation and 
subtracting it from the relative position? would that be faster than to 
use pushmatrix popmatrix?

the geometry I was using so far was simple, but objects could still be 
faster I guess. are you talking about display lists like VOBs or FBOs? I 
have to read more about that and how gem makes use of it.

write as write in c++? or write as write in luagl?
