External integration Issues

PHP will never go away.Rails will never go away. Java will never go away..NET will never go away.

Web Services: The Alternative

Be like the Web!The theory: REST (Representational State Transfer). The practice: XML +

HTTP. In action today at: Google, Amazon, AOL, Yahoo!, many others.

One way or another,we have to integrate.
