other than the turn table implementation.
can u for example alter the code of turn table animation to be able to read camera position and orientation from a text file ?
a temporary solution that works for camera animation will be appreciated from the majority of your users

i can imagine setting up my scene with perfect lighting textures etc from your node editor and then load the camera path and have it running without the fear of incorrect material exporting and internet connection failure during animation rendering.
sorry to be persistent about this, i wish i could join u to help u out
