I don't see that as the use case at all. I certainly wouldn't support 
passing VTD between different processes, systems, or organizations; any 
more than I would suggest passing a DOM or a SAX event stream. The 
proper serialization for XML is XML, nothing more, nothing less.

I see VTD as an alternate, disk-backed object model that competes with 
SAX and DOM within a single program. This could have big advantages for 
memory use and could allow indexing and fast access into the data. 
However, this certainly shouldn't be passed around on the wire any more 
than any other object model should be.
