No such evidence (arguments of the form "nice to have" or "would also be useful" or English dictionary references are not evidence - real world publishing practice is evidence) has been provided to justify a *new* value rather than use of the existing "enclosure" value. If you do find such evidence, document it on a wiki page like "streaming-examples".

Agreed.

It would seem unsafe of me to suggest a rel="stream" without providing 
evidence that this may be necessary  so I  made a study on the existence 
of  "Streams"  or audio that can be played typically in the users 
browser and not available to be downloaded and cached to the users hard 
drive. I found that over 50% our existing examples show evidence of  
streamed audio

see: http://weborganics.co.uk/docs/Stream-Analysis.txt

The trouble is this may be just a "semantic distinction theory"  because 
in order that streams can be played some part of the audio must be first 
downloaded (even if its only a few kilobytes), either to the Browsers 
Cache,  or to  memory by the application that is playing it.

I think that maybe what is best for the hAudio  proposal is that that we 
add the Existence/or not of streams to work in progress 
http://microformats.org/wiki/haudio#Work_in_progress
for any future versions of hAudio pending further examples.

Best Wishes
