The industry has spent the last five years or so to get a conceptual, architectural buy-in for web-services. The standards related to web services, generally referred to as WS-*, too have gone beyond proprietary workshops to standard bodies' technical commitees. Surprisingly all of this effort was driven by developers, for developers and of developers.
Web Services have a reached a point where if they don't cross over from the developer domain to deployment domain, there is a very real chance that this whole effort will be for nothing.
A key stumbling block towards deployment of web services is lack of real products which embody the technology developed in standards and employ the principles behind web services. While every vendor has a web services marketing program, very few have real web services products. No wonder the few customers who had the resources and implemented web services as pilots are being claimed as the reference customers by every major vendor.
