Shawn,

The new ID3v2 Chapter Addendum can do all of these things. It's available here:

   http://www.id3.org/id3v2-chapters-1.0

Unfortunately. it's not widely supported by authoring systems or media players as yet.

There is a Sourceforge project which provides an authoring tool for ID3v2 Chapters here:

   http://id3v2-chap-tool.sourceforge.net/

There is a commercial media player (for Pocket PCs and Smart Phones) which supports ID3v2 Chapters here:

The BBC produces a weekly podcast which includes ID3v2 Chapters signalling here:

This is all the activity I'm currently aware of. If you want any help to get started with ID3v2 Chapters please let me know.
