Calling into doubt my own statement, below,  I looked at the detailed
specs of some of these web-cams.  It seems that their term "pinhole lens"
refers to a very small glass or plastic lens, not a bare pinhole.  Any
more certain info is welcome.

Not necessarily research . . . but some of the low priced web cameras on
the market today use a pinhole in lieu of a lens.
