It is a nifty little third-party launcher for RenegadeX, if it possible for a login via this launcher to create an specific ID - Which can go into the server-side settings for a RenX server then it might be possible for this launcher to be a lovely little SecureBAN for the game. (Ideally working around the game itself by way of masterserver for this launcher and the game-server talking to one another, rather than having to modify the game itself, perhaps a magical mutator can work the login IDs)
Additionally, this launcher has a 'Guest' feature.
