Feature: Dynamic prepending and/or appending of audio to podcast episodes?
I would like to have SSP dynamically append (and I can imagine others could want to prepend) a particular audio file to the end of every episode when streamed. So when an episode's byte-size is calculated (in feeds and headers) it's the sum of the attached audio file and the additional to-be-appended audio file. When streamed (http range requests for bytes) the two files play straight through…
I want to then upload a short audio file to be dynamically added at the end. I can then change that file any time I want, without having to edit hundreds of podcast episodes.
I was thinking this might work if SSP wrote a temporary version of the concatenated audio files and served that. If the dynamic insertion is changed (or removed) then revert to serving the attached-to-the-WP-post audio file as-is.
I realize this is a big feature. I'm wondering if this is something others would be interested in?
