Can you please clarify what scenario you are looking at regarding
multiple consumers? When designing the StreamBuilder API, we looked
at it as a more primitive API which other abstractions (such as
multiple consumers) can be built upon.
(Please forgive me if I am making stupid input - I am in a learning
phase). A very simple scenario would be the example in the draft that
"demonstrates how to use StreamBuilder to load a stream into the audio
tag". In this example the consumer is an audio tag, and new data is
appended to the stream each time the buffer falls below 1024 bytes. Fine
so far, but what happens if the same stream (via createObjectURL) is
connected to one more audio tag, but at T ms later.
In this case the first audio tag would have consumed down to the
threshold (1024 bytes) T ms before the second.
Another example could be that one Stream is uploaded using two parallel
xhr's; one of them could have a couple of pakcet losses and then consume
slower than the other (and if WS could take send(stream) the same would
apply).
If you can please let me know what issue you're trying to address,
I'm happy to discuss the possibilities.
I hope the above input explained the issue.
Also, For future reference, the latest draft is now located on the W3
site at http://dvcs.w3.org/hg/streams-api/raw-file/tip/Overview.htm
Thanks for updating me!

I'm looking at
http://html5labs.interoperabilitybridges.com/streamsapi/, and
specifically at the StreamBuilder.
It has the possibility to generate an event if the data available
falls below a threshold. How is this supposed to work if there is
more than one consumer, and those consumers either don't start
consuming at exactly the same time or consume at different rates,
of the Stream?
