Creating a Word doc on the Client Side From a WebApplication

[nondisclosure007]

I am actually trying to do this and found in this thread some very good
information (begin quote):
{
In ASP.NET you should store and manipulate the word document on the
server.
You can manipulate it either through the Word object model (which is
not
really supported or encouraged, but does work), or you can save the
document
as XML and manipulate the XML.

Then stream the document down with an appropriate content-type and
content-disposition and the browser will open it in Word.
}
The thread is dated back to 2k3.
I'm new to the vb development world. And I have a few questions:
1. If I edit the XML template on the server to send back to the
client, does the actual content of the XML template on the server
change? or is it just edited in memory and flushed when the session is
over?
2. The data that would be going into the template would be coming from
the web page that they are currently looking at (generated by data from
a dB). How would one get that data into the XML document?
3. How does one then 'stream' that data to the client so that it is a
..doc document that the client will then automatically open?

If anyone has links that will answer these questions, I'd appreciate
it.

Ps. The clients w/ have Office 2k3.

thx.
