@BortEdwards Here's a link to a previous thread with the same basic intent.  Didn't stay active very long either...

I like the non destructiveness of the anti-creep mat.  From reports, I expected to have that problem in the Luna Solo tent which is made of,  apparently,  very slippery sil-poly fabric, it just didn't seem to be an issue with my x-lite so I'm glad I didn't preempt it with seam sealer when I was doing the seam sealing.  

Where I do possibly see the need is setting up in a slight incline as I have had to do on other trips.  A small strip of that might be enough to do the trick.  For me it really needs to have a alternative purpose to justify itself though.
