nope, from server-to-server there's a cooldown. which seems kinda odd when you first think about it. why would blizz put a cooldown between moves? To ensure that each server has a stable economy.
In other games with intra-server transfers, it was not uncommon for people to move large amounts of high-value craftables between servers, sell them for gold, sell the gold. In fact, that was quite popular back on UO. You could buy a transfer code for 5mill in game, but could easily move 100 mill of product. Sell your 95 mill on EBay for $10/mill....payday!
