I for one think it would be a great long term goal to allow custom map scripting.
To explain what I mean by this, look at Second Life and Furcadia, and how you can code 'games' into the system.
The possibilities of this are many, from implementing game mechanics to having interactive elements on a map.
You could make a simulation where you have to hunt to eat, find water to drink, and possibly get 'killed'
You could make a giant piano that when you jump on the key objects, they play notes, or leaves russle when you fall through.
You could have hazards, like lava with negative effects, and things such as healing waters that... heal
You could program HUD elements such as stats, health, skills, strength, etc. (perhaps encrypted and saved on the hosts computer)
You could possibly even program your own 'prey' to be on the map.
The best part being: All of it is confined to the map, what happens there, stays there
Much like Feral Heart in general...cough
The worst part being: Some prick will probably find a way to exploit it to, at the worst, be mildly annoying. (If you are careful on what one can do with a script...)
There might also be some bandwidth concern for heightened data transfer of some of these scripts, so something will need to be worked out to prevent someone from purposely creating a bandwidth hogging script.
