Something that might be worth doing is taking a piece of cuben and encasing it in something resistant to abrasion (ripstop or cordura, maybe?) over the majority of its length, and then taping the end pieces to the tarp as the tie-outs.
See stupid little ascii graphic below for what I mean:
Ripstop (sewn to itself to make a sleeve for the cuben).
Cuben (taped to tarp at ends to make tie-out "skeleton").
The cuben provides the immense tear strength that cuben is noted for, along with an easy attachment method that doesn't perforate the tarp itself. The ripstop (or cordura, or...you get the idea) provides the abrasion resistance versus the guyline that the cuben can't.
Just a thought.
