For your wish, the most important part is : how Scawen will be able to dev this for demo hosts ?!
In fact, this is easy to dev it for S1/S2 because you have a "driving license name" for each player...but not for demo
How your server will recognize you ?
IP ? Not really, most people have random ip.
LFS Nickname ? Someone can use your to get admin access when you are not here...
