" This is web technology and reverses"
So what? Internet is first a communication technology, all the "web" stuff that was built upon it is just a use of such communication technology. Desktop application can communicate like any other one - you don't really need that HTML pages display application called a "browser" to do it - you don't even need HTTP (with all its downsides, having being designed to select and display, one-way, simple documents) or HTML.
The actual biggest IT problem is to think everything has to live in a "web page".
