Yes, I would like to see pipelining addressed in the spec.  Right now it is 
unclear if this technique is legal.  The spec does not forbid it, but I don't 
think that is enough, is it?

I'm also not sure what parts of XMPP could be declared as pipelinable.  
Certainly the opening <stream> exchange, but I don't know if the rest can be 
done this way, given the asynchronous nature of elements exchanged in the XML
