I want a coaching service for our website for Counter Strike and I want to be
able to stream a screencast like a web cam. I want something similar to this
website, <http://www.screencast-o-matic.com/>, but in real time. Anyone know
where I should start?

Try contacting the folks who designed http://www.screencast-o-matic.com/

They did it in Java, not flash.

Anyone have an answer?

using a streaming server such as FMS, wowza, or red5, you could position a web cam to shoot your screen, and publish the stream in real-time.

My web cam is permanently fixed to the laptop. A lot of people have that problem. Besides, the quality would be very very low.

you can attempt to use http://labs.adobe.com/technologies/brio/ but its only beta and I'm not sure it fits your needs. other than that, there is no solution available with flash.

Camtasia is the best out there.

By the way, you can download a free 30 day trial of Camtasia and it is the full version.

Sorry, I just noticed you wanted it in real time. Try http://helloworld.com
