Exactly, that is what is so cool about layer 2 circuits. As far as you are concerned the two ends are right next to one another (although on a slower connection than you'd have if they were physically on a LAN). With that in mind you might need to consider QoS depending on how you are going to use the circuit so you don't oversubscribe the circuit.
