Sounds like a perfect example of a use for particles!

Now, why don't you tell us some more details about the problem. There are not many unusual ones at the time...

Is it going to be visible from far_away(billboarding) , or can you stick your head (camera) into the tail(particles)?

I don't want use billboarding, because I wat stick my camera into tail ;).
Where can I find good tutorial about particles (dx8 or dx9).
