Yes, I don't dispute this.  This is not really criticism on RMNET (I just 
wondered why they didn't have a closer prefix, but that was probably an 
artifact).

What is more important is what people get when they DO get the pTLA.  
Some get excited and get N^2 tunnels because they can and provide transit
because it's cool.  Ingredients for a disaster.

At least with less than a pTLA, the damage is limited.
