what are the implications if you dont know the scripting language?
for me? otherwise it's no fun!

3D realtime chat, yes real nice, i'd rather use MSN or IRC ... unless i can get at the insides of the thing..
- can you make objects that seem different to different people?
- can you make an object that crashes somebody's client on encountering it?
- can you make the crash triggerable, for ex. if you "paint" this "flowerpot" "green", it will trigger the subroutine that overloads the client?
- can you hide some kind of "spying camera" in an object?
- can an object make a client access the internet? read/write?
- can you clone somebody else's objects?
- can you alter somebody's objects?
- if you can, can you write a virus?
this is all great fun, and these possibilities are very real in a massive online virtual reality application. currently i'm toying with the same kind of questions for internet browsers (which are almost the same thing as these 3D Client-applications, except that websites are not 3D and not exclusively intended for chatting), the answers to these questions for browsers are of course: yes yes yes yes yes yes yes and yes.
but srsly, i don't have time to get "into" this .. if it's any good, it will consume all my time, can't have that.
