[Bf-funboard] Limits on size

Sounds like the classic "from earth to ant"-problem to me. For scenes
with extreme zooms like "from kilometers to millimeters" as you describe
it the use of one gigantic scene is probably the wrong approach. I had
to do two such animations in the last months (one zooming from a waver
to a microchip and one zooming from a 7cm casing to, well, a biological
microchip). In both cases I created two scenes and used compositing to
add them together seamlessly, which AFAIK is the method of choice for
this kind of task.
Another thought on the way: Even if you succeeded in creating the
gigantic scenes you'd run into real trouble when it comes to animation.
The IPO-curves for camera movement become mostly unusable when moving
from gigantic to minimal proportions, I've had my experiences.
If you really want to do something cool write a python script to blend
camera motion in different scenes an scales, that would come in handy in
countless situations.
