scope of XML

[Jennifer Stetina]

I am looking for information on the following:
XML-supported websites; specifically, a statistic or percentage that
expresses how many of them there are today. 
An estimate or percentage of how big this will grow in the future
How many of these sites are UK-based?  US-based?
If anyone knows the answers to these, or knows someone who does, please
contact me.

I gather that what you are proposing is that the Java program listen
directly for the HTTP requests? Could this piggyback onto a web server
somehow?

Another proposal I found was using XML-RPC (http://www.xml-rpc.com). In the
POST method inside your HTML you can execute an RPC and use as the transport
mechanism XML, both as the request and the reply. I haven't figured out how
your Java program would register itself with the Web Server, to expose the
RPC calls that it is expecting. This would require a bit more research, on
my side.
