Using a single FLV to play video simultaneously in two places

Is there any way to have an FLV load into your flash movie as a single download, but have it play in two different clips simultaneously before the flv is done fully loading?

In other words, how can I mirror a progressive flv in two clips with it starting to play after a preset buffering percentage?

Is it possible? I’ve seen a single clip used twice at the same time with the use of the streaming server - http://www.linkinpark.com bbut I don’t know how to make it work with a progressive download.

HELP!!!
