The issue i see with either radio towers or fire's is that you will need a lot of equipment (and possibly) people to accomplish battling ghosters. While i do understand it can be a problem in fixed locations, like for example the Airfields and the Main cities. Which will give either side the option to realy set up a base somewhere and other the drive to take it down (aka. group play, f/e friendlies taking over Elektro by blocking out spawns for hoppers and bandits) ... but, i think just setting a perimiter isn't enough, if your spawnpoint happens to be blocked this way, then ones option should be to spawn at the beach or goto another server. And i don't think this is harsh, see, if you are not around to defend your spawnpoint (aka. you are sleeping/not logged in) than it's fairly reasonable to assume you either been captured or just slain in your sleep as this group came in to set up this radio tower. You may have been able to take one or two down with you but thats about it, and afterwards you would spawn at the beach with no stuff at all... so IF your spawn is compromised at this particular server, you get the option to spawn at the beach and keep your stuff, or you goto a server where this location isn't compromized... But the ghosting problem isn't just a problem there, it occurs everywhere and everywhen in the game, so there should be an easy to obtain item that gives a player the time to get away from a location someone else just alt+F4 outof, and my first thought was Flares, these only last 5min, so they only cause a fairly short period to block of an area for spawn, but at the same time, they give enough time to get out of that location and perhaps even to a good location to take off this person as (s)he tries to ghost back in. Flares are also so commen that everybody can have 'ghost' protection on them after the 1st or 2nd building they loot. A third thing that just dropped in my mind, it would be kinda cool if this radio tower could be modified to send out a signal that prevents Infected from spawning in a certain radius. Not prevent them from comming in if lured or drawn by loud noises. But clear spawning would be nice, that would give friendlies and bandits the option to set up relative safe zones. While a safe zone might brush against some people's hairs, on the other hand it's exactly what people will do (and have done through the ages), build something that keeps nasties out. Seeing buildings and barbedwire doesn't do much, as the infected just glitch through them, setting up a radiotower with an Infected Modification would atleast create a relative safe zone. What does need to happen though is that gas/petrol becomes limited in supply, meaning that this Infected repellant can only run so long, it will have people organize raiding parties to nearby gasstations in order to keep them running, etc... Perhaps a radiotower can only run in one mode, either repell spawning of people or repel spawning of Infected. In which case a choice has to be made, you can still somewhat secure your base with barbed wire, and other items to create a somewhat save area from people, or when you run two towers, you burn through fuel twice as fast. PS. Now that a generator is planned, it would also be nice if we can run lights off of it, this will help setting up safe zones at night, where you'll be able to see people comming in and can inquire them of their motives, or shoot them on sight...
