I just found this free service, that is pretty cool. (no I am not a shill, I am working on some windows mobile software on the side)

Dear Blizzard,

You are dropping support for LAN play with Starcraft 2 and Diablo 3, so high speed internet is required for multiplayer, and if your Battle.Net servers are down for any reason then I can't play multiplayer.

I have been waiting breathlessly for these games, so that I can have LAN parties again, now all that was for nothing. You have destroyed my hopes.

Because of your decision, I am canceling my World of Warcraft, and my wife's. And I will never purchase another Blizzard game as long as I live.

Sincerely,
