Flash Streaming For RoR

I was fiddling with some video flash streaming code the other day, and came across a great script by Stefan Richter that would allow you to seek to any position in the video without having to wait until that part is loaded first.
I have managed to port the code to work on Ruby on Rails. So you can get the flash player from Stefan's post, and if your server is running RoR, here is the server side code to get the job done.
