I have to perform some load testing on media servers, specifically Windows Media and Real Helix. I am going to be using Windows Media Load Simulator for testing the WM streams, but does anybody know of a simliar tool for testing against Real Helix Universal Streaming Servers? I will initially be testing for 100 concurrent users, but will be moving on to test against 1000 concurrent users. The users will be split between the WM streams and Real streams.

Thanks for any help.
