marcoR, this would be a "gateway" to the other playerworlds.
I for one, would like this idea, perhaps disable the serverlist or something.
This is how playerworlds originally worked on Graal, -- you had to walk through some sort of teleporter. (Anyone remember the teleporter in Stefan's house on old classic?

)
The only difference now, is playerworlds have their own servers, rather than on the same server as it was before.
