(1) there's a lot good with lite-C. for one thing i believe it is faster than C-script due to it being pre-compiled. u can write any windows application in lite-C without using the actual engine. u can call directX functions or openGL functions (but i don't think you can do openGL while using the engine since it is directX, but someone else can correct me on that). if you learn to take advantage of lite-C, you'll basically be learning how to program in C (though by the looks of your signature, you probably already know C).

(2) like i said, you have access to openGL, directX, and windows API. the compiler is also stricter, so some people may have a few initial troubles migrating from C-script to lite-C. u can use structs in lite-C! structs are great.

(3) it's been done before in C-script. quite a few times. there's nothing stopping anyone from doing absolutely anything with lite-C.

good luck
