Dylan, in payroll, when we want to move money to lots of people at a time, we send a text file, or an excel spreadsheet, or even just take a printout to a processor or bank.  There is no amount of activity (especially when the bank is charging a hefty fee for each wire) that would ever make a bank say, "Whoa there, that's too much, it's going to take us days/weeks to do all of this".  They would jump on that shit like throwing fresh steak into a pack of hungry stray dogs.
