[IMC-Video] cloning youtube?

[Echograph]

John:

Wow. Thank you for working on this. It would be a great addition to the 
IMC network and allow us to compete with YouTube better.
I'm forwarding this to techies with LA-IMC who are also interested in 
this.

At LA-IMC we are currently embedding video with HTML code but this only 
works for video that we produce and upload first to the server.
here is a link to an example

http://la.indymedia.org/news/2007/06/200948.php

But our users can not do this. One thought we had was to write a 
routine that added the embed code when the user posts video the way we 
do for audio files.
But what you are working on is much more powerful.
