Before you get into this, have you considered the bandwidth required  
to play back the high quality content you've captured over the  
internet? Even greatly compressed content would be a nightmare. You're  
better off using mythweb or vlc streaming which is well documented in  
several places and then just worry about forwarding port 80.
