I am curious, partly because how-ever it is done might also serve or be adaptable to moving funds into and out of anoncoins, or any other coins for that matter. ?
If it is customarily currently done by having a mule/bagman fly offshore smuggling as many $100 bills as he/she can manage to sneak past customs, maybe having the offshore bank turn it into anoncoins for you might be useful so the offshore bank itself does not know about every payout you make with the funds between handing them over to them and sending another mule/bagman to them to get them back as fiat?

Just because it's offshore banking doesn't mean it has to be some sketchy operation. There are many reputable offshore banks that are actually just a branch of domestic banks.
For purposes of this exercise, these aren't the banks that the majority of "private wealth" are stored in.
