I would say that GeoIP would be the best. And those users that need to travel need to pre-request travelling access through a captcha-protected AND geoip restricted web interface prior to travelling. (but once opened, they can extend access out-of-country)
And then they need to specify time spent away. (which will be deducted from their total) Also to prevent people from opening travel access without need, make it so they can open a maximum lets say TOTAL=30 days per 180 days.
