This thread keeps getting derailed whenever someone suggests trying this. The only way for the dvds to make it overseas is when the recipient wants to pay the postage, but it is not talked about, to keep this from "selling" the program, legally, that is.
The chain letter idea, the next guy in line makes copies and pays the postage, so it is not construed as selling anything, but the postage overseas makes it prohibative.
It is hard enough to keep theys guys holding up their end of the bargain as it is.
