  Actually, it can be done like this. I would have to use an unlimited 
  dimension though as I do not know in advance how many frames I'am going 
  to have. The problem is not the 2d data itself, it is the fact that we
  are scanning through space and store a 2D at each step. Even compression
  would work with this. I got to use it, we are talking 100+ frames with
  128*128 (finally *3) at each step.

  My only point is clarity when browsing the file. Each frame in a vGroup
  with its associated parameters just looks nicer and clearer. In C I would
  use an array of structs for this. 

  Anybody else with strong feelings about this?
