While there are similarities, there are many differences.

This smallx technology was designed to process XML infosets.  The 
convergence on
XML pipelines between Orbeon and smallx is just validation that it is 
the right
idea for XML processing.  In fact, there are many other projects 
XML pipelining technology (e.g. Cocoon, SXPipe, Markup Technology, 

In my case, this code base has been around for about four years and so 
my the release of Orbeon's software.  Of course, my smallx code wasn't 
either.  ;)

In addition,  my essential requirement is that it support streaming of
infosets.  I process very large documents and need to keep my memory
requirements low.

The Orbeon Presentation Server project/product is really good 
technology but
I'm not certain that the XML Pipelining technology is separable at the 
time.  In the smallx project, the XML processing technology is a 
completely separate
project (internally) from the J2EE servlet container integration.

Ultimately, while I use the XML Pipelining technology to implement web 
and web applications, I have other uses in processing XML for 
bioinformatics outside
of those contexts.

I would say, convergence on *one* XML pipelining specification language 
be a really good thing!
