This needs to be a playertype. I've run into several problems with this thing.
First of all, if you use any node hiding or unhiding command, the banana will break and when nodes are unhidden, you will look like crap.
I figured this out with Bushido's Energy Shields and the Invisibility Watch set. They will ALWAYS break with them and I was forced to remove code from the energy shield if I wanted to use /banana in my server.
So if you feel like using it in some server, just let it be a Throwmod or something.
