I think it is certainly a reasonable way to provide accessibility. I used
this approach at http://www.w3.org/WAI/AU/tech-scratch/tables (which is just
some stuff about how to get the user to give a caption for a table).

  Geoff,
  
  If people agree that this is an o.k. thing to do, then we would include it 
  in the techniques document.  The current phrase that I pointed out would 
  probably be reworded to something like:
  <blockquote>
  Equivalents for sounds can be provided on the same page as the sound or in 
  a separate file.  If in a separate file, provide a short text equivalent 
  (like an "alt-text") in the text of the link to the text transcript or 
  description of the sound file. The link to the transcript should appear in 
  a highly visible location such as at the top of the page. However, if a 
  script is automatically loading a sound, it should also be able to 
  automatically load a visual indication that the sound is currently being 
  played and provide a description or transcript of the sound.
    </blockquote>
  
  thoughts?
