Ok, The Bisque situation is much improved since I last posted. It seems obvious now the "right" approach all along was to install a separate Bisque engine on bovary itself. Wish I'd perceived that earlier. Anyway, now I can develop modules there without disrupting anyone else, and I don't have to wrestle with firewalls or configuration riddles-of-the-sphinx.
I've got the 4D module alive there, i.e., it starts; but I've encountered (or re-encountered?) a bug in the C++ inference code. So we begin another round of getting the CVPR code fixed up, with the original developer. Hope that doesn't take too long.
