[jdev] Multiple/parallel file transfers

I saw the fast-mode article last month while researching how to
implement the bytestream file xfer and I thought it was interesting to
look into at a later time. Since you've reminded me, I have a
question... given the following :
<iq from="bob" to="alice" type="set" id="s2">
<query xmlns="http://jabber.org/protocol/bytestreams" sid="mySID">
<streamhost jid="bob" host="private.bob" port="8000"/>
<streamhost jid="bob" host="public.bob" port="8000"/>
<iq from="alice" to="bob" type="result" id="s2">
How do you specify which streamhost was accepted in the reply?? All I
can see is that the streamhost with jid "bob" was accepted, but that
could have been private.bob or public.bob. You do mention something
about the initiator throwing out an extra <CR> (extra??? so there were
previous ones???) into the socket stream... does this mean that the
target is to expect a carriage return from the initiator in the
streamhost of choice?
