Actually what neteller is likely to do (if it doesn't already) is simply issue banker's drafts to settle accounts - in the UK if you have money lodged at a financial institution there are two sorts of 'check' you can draw..

One is the usual one drawn on the account held in your name with that financial institution - of course you sign that one and the details on it will show which account it comes from - if you don't have sufficient funds in the account it will bounce.

The second is a banker's draft - which is a 'check' issued by the financial institution itself and for which that institution is liable - it would just be a draft issued by say RBS pls, which woukdn't indicate the customer name on it.

In UK domestic use the main point of these is that banker's drafts don't have to 'clear' - they are backed with the full funds of the issuing institution and so can't bounce unless that institution itself goes bankrupt - so they are treated (if issued by a reputable bank) as being as good as cash..

So if neteller just issues its payments to US customers in that form it's going to be very very hard for any US bank to know that it indicates a gambling transaction.
