Quote - I've managed to work with a pipeline to an external .exe (see my recent thread on convex hulls and popen).

Do you have the C source to the exe that shows how the pipe works on that side of things?

Quote - I can't find any examples for using a .dll instead of a .exe, unfortunately.  And, for our purposes, porting the linecast_loop over would be a major revision.  Yipes.

Not a big deal... except for the additional data it needs (the region arrays to loop through, tripoly, vertex, normal and other data arrays, etc).  Heck, it could/should (might as well) compute the weight tables as well.
