GEO IP Pricing Structures?

So the fact that CCBills regional pricing option is doing well for me on Condom Cash got me thinking...

If certain members from countries outside of the US are actually spending more than the regular membership price displayed in dollars, do you think it would be worthwhile setting up some join pages that these surfers from non-us countries hit and nobody else?

For example, users fromm the UK, geo redirecting them to a page that displayed a set price in Sterling, surfers from France, redirecting them to a join page that displayed a set price in Francs?

It seems that surfers from some countries are actually willing to pay more for a porn site membership so im wondering how these surfers can be marketed to in terms of raising prices only for them.

Your thoughts, would something like this work without the use of CCBill regional pricing?
