Broadcasting from several sources with the possibility user authentication?

Hello, we would like to purchase Flash Media Interactive Server 3.5
to solve the following problem


1. Broadcast network internet lectures on a paid subscription, with the
    possibility user authentication.
2. Broadcast video and audio.
3. Broadcasting from several sources (1 camera, 2 camera, TV tuner, etc.)
    within a single stream with the possibility of the user to choose the viewing
    source, other sources at this time, you can view the preview.
4. The intended audience for 10 000 users and more.
5. Estimated flow rate of 1 megabit per second.

Our questions:
1. Is it possible for broadcasters to use a single server, or they need more?
    What configuration?
2. Does Flash Media Interactive Server 3.5 multicast?
3. How to make the system user authorization? Additional software, plug-ins?
4. How many users can simultaneously connect to the broadcast Flash Media
    Interactive Server 3.5 and how we calculate the bandwidth and outbound traffic?

    1. Yes... several broadcasters can publish to a single server. Configuration will be dictated by your application architecture and anticipated usage requirements. You can republish the live streams to multiple servers to accomodate large audiences.

    2. FMS 3.5 does not multicast. Each client will consume server side bandwidth at a rate equal to the bitrate of the video stream

    3. FMIS (interactive server) supports authentication through a C++ architecture, and through server side actionscript. Authentication is not built-in... you'll need to develop your own authentication mechanism (see the recent thread on the topic).

    4. You can caluculate bandwidth by multiplying video bitrate by the number of clients publishing and/or subscribing to the stream. User capacity will be govorned by the capability of the hardware, and by the available throughput of the network interface. Unless you're running 10gigE network cards or very low end servers, chances are you'll max out throughput before you max out hardware.

    At 10,000 concurrent clients, you'll definitely need more than one server. For that volume, I'd plan for at least four, and plan for developing an architecture for distributing the live streams across multiple servers. A good place to start is here:
