While you're using XML, there doesn't seem to be a way around the  
problem as the answer is to stream the data, whereas XML is formatted  
in blocks. Given that constraint, the answer seems to be to use an  
intermediate server providing the API you want.

That is to say, instead of a client/server arrangement, you want a  
client/api-server/server arrangement... where the database has no  
state, but the api-server does. That arrangement is scalable as you  
simply bung in more machines as you start running out of memory/CPU/ 
network, without the cost of a database per server.

Needless to say, I think XML is a re-invention of the wheel, with  
spanners and swiss-army knives poking out of the treads, and I refuse  
to touch it. :)
