Advanced Seeking in FMS3

I need to be able to stream a live feed to the streaming server and have it also be recorded for later on demand playback. I need to be able to apply markers to the on demand files via XML or similar method, so that advanced seeking can be performed without waiting for the file to be fully downloaded.

I need to basically be able to provide a table of contents for 2 to 3 hour City Council meetings, and the end user would be able to jump to any agenda or section of the video that is listed in the table of contents.

The feature list for Adobe Streaming Server has something called Advanced Seek, which I assume would allow this type of scenario.

Can anyone point me to any references that might be useful for designing this type of application?

Thanks, so much for reading.
