Can you use an oveseas proxy to mask a US IP address?

Question

Hello, This is a bit of an odd questions posed to me from a client. He owns a website, and his affiliates require him to have an overseas server.. HOWEVER, he does not trust the data, etc and likes the service he has with his existing dedicated server in the US.

So, the question is.. can he 1) pay for an overseas co. to proxy the US IP, only showing the overseas IP to visitors or 2) purchase a small shared or VPS server overseas and setup his own proxy or 3) is there a way to Mask his US IP in a way that wont result in his affiliates pulling his account ??

Any other recommendations, even to the extent of reliable, high bandwidth overseas hosting providers is greatly appreciated ;)

Thanks
