Paying for Web Services. Jon Udell: Paying for Web Services” Web services and generic local components are two sides of the same coin. Both can be powered by free software, and both can create business opportunities.When technology hype reaches a crescendo, I instinctively reach for a touchstone ? a humble example that grounds me in reality. This week, as I was almost deafened by the uproar surrounding web services, I found one such touchstone. Here's the scenario. I maintain a Zope-based extranet site for a small group of collaborative knowledge workers. Part of the site uses the Zope calendar tag to keep track of events, and I was asked to arrange for various folks to be notified, by e-mail, on the day prior to these events.” [ZopeNewbies]
