FWIW, Nikki & I have both have Neteller accounts and both have accounts on the major sites. We've made support at all the sites aware that we are husband and wife. Her Neteller is under her email, mine is under mine. We've had NO problems.
The only thing you WON'T be able to do is tie both Neteller accounts into the same bank account. But that's what the PokerStars Transfer Funds option is for!
