You and I may agree, as programmers, that the STL format has
shortcomings, but from a user's perspective it "works." What are the
"killer app" features of PLY or COLLADA that would motivate vendors to
implement support for those formats? (Or be neat enough that the users
themselves asked for support from their vendors?) Neither the CAD
packages I have access to nor the preparation software have support for
it currently.

Out of curiosity, whose specifications required NDAs? The Materialise
spec seemed to be offered free here, though the link is dead now. And
there are an awful lot of citations of the "Stereolithography Interface
Specification" on the web, which hopefully indicate that the spec by 3D
Systems is unencumbered (even if it is not available electronically).
