nossr50:
I intend to do my best once the sdk is released, as it was pointed it's basically impossible as the game surfaces are anything but regular. In the valve portal movie you'll notice everything is absolutely flat, and even then they never fire portals at edges, for example where the floor meets the wall. still I have some ideas for making it work, and at the very least I will be able to have the portal run parallel to the targeted surface instead of perpendicular to the viewing angle. (see attached diagram it makes more sense)

If you want the mod I edited to work on the demo just take the script and def folders and drop them into the base folder DO NOT drop the pak000.pk4 in there or you will be very sorry.
