Did a bit more gooling. Coming up mostly with non-professional opinions, like ours.
However, please see
this article, for example, written by some attorney, that says pretty much what I've said.
Or maybe he, too, shouldn't do business in the US of A.
EDIT: Oops. This article is the same one I linked to yesterday from Nolo Press. I don't know if you're familiar with Nolo but they're a very reputable and successful US (yes US) company, publishing legal assistance for the masses. My questions still stand.
