Notes

• From what I’ve gathered, there’s no way to host this on LAN.
• MW2sa, a popular kick tool, has been discontinued, but there are alternatives. This doesn’t pertain to what I’m trying to accomplish, but it’s also interesting to me.
  • It’s understandably restricted, but I can’t help but feel a little sketched out to sign up to get access to a black-box .exe. Probably won’t be trying that one out.
• MW2 Lobby Tools also exists, and I may give that a try
