Well there is an opportunity here; one that goes to the heart of the 
entire enterprise.

The reason for web services -- as opposed to simply using Internet 
Exploder -- is that a machine oriented interface is ultimately very 
powerful for automation; in this case automated use of the web.

One of the most powerful motivations for using the Internet at all is 
that people can make late choices, and that they can use the web to find 
what they need as well as do what they need to do. Otherwise, why isn't 
everyone doing UUCP?

What's true for people, is also true for their programs; giving up on 
this goal is tantamount to going back to the LAN/Intranet way of doing 
business. We might do that, but it would represent an enormous wasted

Unfortunately, this is simply not true. We cannot simply `trust' the 
semantic web folks to do their jobs right and solve our problems.

I didn't notice it fall off. Maybe I missed something?
