Tips on Running an Effective StarCraft II Tournament

Community-driven tournaments are essential to the health and growth of StarCraft II as an eSport. Follow these steps to make sure that your StarCraft II tournament kicks off flawlessly.
License your event -- Obtaining a license to run a StarCraft II event is easy (and free for the vast majority of applicants) and the application only takes a few minutes of your time! Head on over to our Tournament Submission Form to start your licensing process now. Approval time will vary; most events will be approved automatically after your submission, and others will take up to a couple weeks, depending on the complexity and level of licensing required for the event.
Follow the rules -- Head over to our Video Policy and StarCraft II EULA pages to find out more about what’s permissible when it comes to broadcasting and running your event.
Help us whitelist your IPs -- This is a very important step, especially if you're running a mid-sized or larger tournament. The reason for this is because if Battle.net detects large numbers of StarCraft II players trying to connect from the same IP, the IP range could get temporarily blacklisted, making it impossible for your event’s participants to play. If you’re running an on-site event that will have lots of people connecting at once from a limited range of IPs, send us an email with the subject Whitelist Request and include your event’s information as well as your venue’s IPs. We will only provide whitelists for licensed events.

Like I said, I've run multiple successful tournaments as the founder of the New England SC2 League (http://www.nesc2league.com), and I could have wrote a better article than this about "running" a tournament. I'm disappointed Blizzard :(
Keep the requirement for connection to blizzard servers,but allow hosting custom games in LAN mode.These games could appear in players history with a (Lan Mode) tag,or not appear at all.
You still validate the authenticity of the game's license and you allow for a fair lag-free enviroment for tournaments.A Win-Win situation,so why hasn't it be done yet?
