I guess we might have caught up by the fact that EIAS can only acept Tri and not quad meshes. If quad meshes is the native format in EIAS and the conversion from Quad to Tri is the hidden process in CAMERA. I suppose life will be much easier.
We then only need ONE standalone EIM as before as long as EIM output Quads meshes. Then we can have a simple but adequate Quad SDS editior within EIAS for last minutes changes and vertex level editing for animation or editing/ adding in round corners/creases to improve render quality.
If this is possible, I think many import issues will have an easier path to resolve as most current modeler output quads meshes. Form Z need a new FAC format to write to Quads. If EIAS also export Quads to other organic modeler via obj. format to take advantage of more advance SDS tool sets. I think EIAS will ZOOM ahead.
Just another one cent if it does make sense. I am just guessing, I may be wrong. Cheers.
