Actually, WAP is already well on its way to the semantic web. So WAP actually is well on its way to being an interface to the semantic web already. The WAP architecture contains interfaces to the user, the defice capabilities, the transport network, the bearer network, functionalitites external to the user agent, interfaces to the information, and of course administrative interafces. Some interfaces , however, are standardized from the other end. When they are, you have to adapt to the interface.
First mover wins.
And WAP certainly is not the first mover in the Internet or in the information that is base for the services. But there are several areas where it is unique, on the other hand. The mobile world, the Internet, and the telecom world. It may be that it is a crossroads instead - that the WAP architecture can become something totally new. And that is, as you understand, what I think.
