Update from Chris (9:10 p.m.): I am pretty sure, based on current returns, that Brown will win. Expect the race to be called for him shortly.

I'm going to go read up on the Libertarian Party and get drunk. See you guys in the am. (PS- I hope I wake up with a hangover and completely wrong.)
ADDED- 9:22MSNBC just reported AP called it for Brown, Coakley has called and conceded to Brown.
