I'm curious as to what is the maximum number of countries outside Europe it's possible to visit on a *A RTW ticket, preferably with no surface sectors. Is it actually possible to get a different country with each coupon, or would there need to be some doubling back? Are there interesting things be done with multiple-stops-on-one-coupon to push that up higher?

Will the answer be different once Continental joins and offers some more interesting trans-Pacific routes?
