Bikeman,
I think your wait-and-see approach is the correct one. I too, am doing the same. There are certainly precedents being set to allow US affiliates to market to International Customers (Mirage and Sands are leading the way here).
I’m waiting to see what happens with WTO early next year as well. For now, I’m not marketing to US customers either. To do so, is clearly in violation of the new law.
