Just seeking thoughts on this. I have had to integrate many disparate packages that stepped all over each other. Some hogged all kinds of physx layers. Others had subsystems set up in one way that made integrating the second package a subsequent PITA. Does a purchaser have a right to demand integration of your package with another? If the integration cannot be done whose fault is it? In have my opinions on this but looking for other views if they are different or congruent.
