assuming the bike has disc brakes, hopping up on the left side could be pretty expensive as well. if you thrash the rotor, you're not going to be riding home. if you thrash your derailleur, you can usually get home.
personally, i'd rather side-up on my left side as well, but if i was trying that stuff, i'd be using rim brakes for sure.
it sounds like he bent the RD cage as well as the hanger. the hanger is pretty easy to fix with the DAG, the derailleur itself can be pretty tricky, depending on how damaged it is. take it to the shop you bought it from and they should repair it for around $10, if not free.
