Yes, for sure. Right now it only let's you put in a valid geohash, but I will open that up. For the sake of keeping things simple ill probably just keep using the kind 2000 though. Not sure. I need to think about it.
It depends of what the 20000 kind wants to be. If it is just for geohash-based conversations I don't think it is a good idea.
