Great stuff. I know you've said you won't be updating but just incase. Here are the bugs I've encountered:
- No limit: Doesn't work.
- Non-resetable host settings: Once you picked a map etc you can't change the settings (you can but they don't take effect unless you restart MW3)
- Speed: Doesn't work
- Freeze all: Doesn't freeze anyone, it just teleports them above your head
