Is there LAN play for this game?

Is there LAN play for this game? I was thinking of getting a 2nd copy cheap with the current Friday Special The Indie Gala bundle but need to know if there is LAN play as I already have this on one of my household's Steam accounts.

I asked this over a year ago and want an answer. Is there LAN play for this game? Also does online MPer work for this game? I already own one copy of the game but don't want a second copy if I can't play LAN or online with my son.
