I've never done it on a core switch, but at the edge doing traffic prioritization is dead easy. I imagine that doing it in the core just means that you need to make sure your core switch is up to it. For example, Force10 units are likely to handle it, Extreme units are guaranteed to

I've thought long and hard about this, mostly from the perspective of regional ILECs too small to implement MPLS. QoS should be sold in 80k 'channel' increments. You, the carrier, don't care what the customer is marking as DSCP EF, you just accept and accelerate the first 80k x number
