I had thought about doing the same thing with something like the 1/16" spectra guy line that speer sells around the perimeter of my cat cut tarp. I also had the idea of putting the guy line in the flat felled seam on the ridge line. If you used the perimeter method with a square tarp, like a JRB 8x8 or the Gear Guide tarps, that are pitched on the diagonal, it would help with the sag issues.
