Well, given that ListPlot3D creates surfaces (and not a line in 3D space) it
is definitely not so simple to extend its functionality in the way you
specify.
One could write a package though, that takes an array of points in 3D space
and creates a mesh of polygons (so that four adjacent points in the matrix
would define a polygon).
ListConvolve with the right arguments could do the trick, I think...
