It is, and has been for a couple years! Currently weekends only, alas--but great, especially if you've got a place to stay up there.
If you're in the Denver area & looking to get to the slopes without having to drive yourself, there's a number of organizations and clubs around that charter busses; I had a good three or four year streak of working while riding a bus to and from Winter Park/Copper Mountain on Tuesdays and getting some turns in midday when my life still fit well around that sort of thing. (I've small kids in daycare now, so am on hiatus from that arrangement.)
