If you’re gonna stream your video you need a stream server. If you’re gonna use “progressive-download”, or “pseudo-streaming” you may realize it yourself on any php or similar web server. Compressor can encode movies optimized for streaming/downloading with proper meta-data. Use h.264 codec for .mov .flv, .mp4, .f4v container.
Adjustable bitrate means that you have a number of files with different bitrates that client web browser can choose from within depending on bandwidth.
