well really i stopped writing on it soon after i had posted my start at 
the gem-dev... :-(
hopefully i'll find time again (and to fix the avi-player in windows, 
and and)

well i am not sure whether it is a good idea to depend on the extension. 
(yes  i know that the whole redmond os is wrapped around that, but this 
doesn't prove anything)

i thought of one (abstract) class that defines the data and the 
render-method; and child-classes would then implement the readers  (aka: 
open()-method)

i would then call each loader with the given filename and the first one 
that reports that it supports it (even if this decision is only based on 
looking at the extension) will get the job.

simple enuff...

the problem why i got stuck is, because i couldn't decide how to layout 
the data (one big vertex-array for the whole model and references to 
this pool for the submodels (like in OBJ), or arrays for each submodels 
  (might be more general) or...); sounds ridiculous, but i quickly got 
tired...
