Your camera object idea sounds like the most logical solution to the problem.
Since Gary did *mention* that cameras will be handled differently in R5 we can
only hope <g>.
At the barest minimum, 3DS could allow you to specify a provisional "up" vector
for the camera, so that 3DS doesn't have to calculate it itself. Instead it
could use the provisional "up" vector to calculate the exact "up" vector used
by the camera. This would prevent all these quaternion singularity problems
since allowing you to explicitly specify where "up" is for the camera means
you can control the camera roll exactly as you want.
