Again, you missed my point....or I am not making my point clearly (apologies in advance). I am NOT saying its NOT POSSIBLE to figure out where stuff is if you compare the foreign language Overtures to the US/UK ones. NOR am I saying that its NOT possible get your english keywords listed on foreign language Overture by going through US/UK customer service. I am saying there is NO STAND ALONE ENGLISH LANGUAGE VERSION of those sites; such that, you sign-up WITHIN the foreign language site and have you results appear in the respective local results.
In any case, comparing the sites still doesn't help you figure out what money conversion rates are. Thus, there is no way to do register without going through the US/UK sites first and then asking them to transfer them (which I acknowledged as possible earlier).
The difference is having a true english version site of a foreign language PPC so you can register with NO COMPARISON SITES OR OUTSIDE SUPPORT (customer service).
short answer: YES.
In general, I agree...but same cases, NO. But that's another story and its wasn't really my point. ;)
