I just noticed that the Audio module also adds a section in the "History" section of user profile pages, offering a link to hear recent audio files uploaded by that user. You can see an example on my profile page. This will not include any audio "in progress" (i.e. Track 'n' Stack projects). But it includes all the rest.
I would encourage those of you who record to post as much of your own content as you like as audio nodes to the site. BPing probably gets quite a bit of traffic, so this could be one more vector to get your stuff out there. I plan on posting all of my James, Not Jim tracks here as well as at the JNJ site.
