Maybe I am missing something, but what do you mean by "the binary data stream
which contains the opening <stream:stream>". Do you mean non-ascii? If so,
isn't the opening <stream:stream> ascii?
The current stanza flow is shown below. There are currently three stream
restarts, indicated by the <stream:stream> stanzas. I think what is proposed is
just to eliminate the 'extra' <stream:stream> stanzas (2 from the server, 2
from the client).
Thanks
