Flash streaming video

hi,

ive been asked to produce a web site for a new movie to act as a teaser…mainly as a showcase for the trailer. my question is…i havent really used video in flash before. Is it straightforward and can it be streamed and not embedded into the flash file as this gives huge download times! I want to know if its gonna be a headache or not as the job needs to be real quick and wont be well paid.

thanks.
