FMS design issue

Hi all,

I'm a FMS beginner and i have a bit of a design issue.

On the one hand, I have a remote site with 2 serveillance cameras that stream MPEG4 using a video server with static IP.

On the second hand i have a FMS in the headquarters that should publish the streams live to multiple Flex clients. (Note that the FMS is remote and there for i cannot use the Camera object)

How should i begin?

Should i write a server side application that grabs the MPEG4 stream which sits in the headquarters and using the Live Encoder publishes the streams as flv file to the FMS (if so, how does the FMS intracts with such application such as java or .net application in the meaning of streaming)?

Are there any other way that you may think about.

I'll be very thankfull for your help. 

Thanks in advance.
