I currently stream live video using Amazon EC2 with Wowza streaming AMI.

I require a script to control instances based on demand. I need more instances created in peak times and then reduced in off peak times.

We currently use a flash client to connect with one EC2 instance .. this needs to be upgraded to connect to appropriate instance when more or less are created.

Detailed knowledge of Amazon EC2 and also Wowza media servers is a must.
