Quote - we don't have an exact figure on when daz started working on D|S as a poser replacement,
but I daresay it was not long after they split off from zygote.

Ain't saying.

Quote - And I would imagine that there was probably some reverse-engineering at play when the initial betas of DS were built. Just a hunch.

Possibly, but I doubt it would've gotten them further than the fora discussions of it did. Qt and 3Delight are off-the-shelf parts, so to speak - both are open-source to boot, so behaviors can be determined fairly quickly for them.

OTOH, there'd be precious little that could be incorporated from D|S into Poser - quite simply, they're just built far too differently.
