Does FMS allow Bandwidth Throttling of Streams?

If I want users to connect and either stream or progressively download a video, can I turn on a limit for the bandwidth? Say I want people to download a video encoded at 200kbps. I dont want their networked hit too hard, which would happen if they simply started to progressively download this with no limits. Their flash player would simply try to download the entire file as fast as possible. Instead, I want to throttle their download bandwidth to 210kbps, so that the download happens more slowly, but still fast enough for the video to play the downloaded segment without interruptions.
There IS a way to throttle upload bandwidth on video cameras and microphones - I saw this in the tech descriptions, but cant think of the method offhand. But its for when users are tossing live video from their web-cam to their server - the server limits the bandwidth. Is there something like this for downloading/stream with FMS?
