I'm currently sitting in Doug Purdy's Web services versioning talk here at TechEd.  The fact that we are here with Doug reminded a few of us of his earlier talk where he philosophized on the connectivity of applications.  Apparently he will be talking a bit more about that concept in this talk.  The phrase describing this concept is:

There is only one program ... and it is still being written.

That left us to wonder: boy, that must be some kind of license agreement. :-)

And of course ... it is still be written.
