Hello Dirk Reems...
I may have a solution for you, depending on how you are directing your 404 traffic.
SEXMoney.com has over 250 paysites in 25 languages, spanning 40+ niches.
I would create a script that would direct both your domestic and intl. traffic to a site in the users native language, with the appropriate billing solutions. This way you can harness all of your traffic no matter where the user is originating from.
We pay in FULL on ALL Exits and ALL Payment Methods...
If you have a moment, if you can contact me, so I can discuss this in more detail with you. I can be reached via ICQ, Phone or E-Mail!
Warm regards,
