4! if your shadow is moving on a flat surface, what about a _child polygon with a texture 50% alpha on it? if you parent moves on the x axis (up or down), use only y movement to your shadow. you could also resize the texture according to the upmovement of the parent. use perpenducular to stay "logical" mixe both updown position of parent and light position to calculate ideal position...etc
5! take a peek at Havoks, there is a script into a carsteer demo.dir, with a shadow even on not flat surfaces. but basic trick is same as above. tricks enough...
