Well, essentially by being a standard. With XHTML and XForms, you can author one application in one markup language, and in the long run, as devices, whether it's a WAP (WAP now is XHTML-based in the new version, desktops are doing XHTML) as all the different devices are able to browse XHTML, than you have device independence. And the special power of XHTML and XForms, for instance, the media tags and things like that, media queries, is such that you can express enough of the variety that you want on different channels in the XHTML XForms that different browsers can do their jobs appropriately on these different devices. So that's the good news. In the short term then, what you will be doing, and how to get off the ground quickly, is to use some sort of proxy technology that takes XHTML XForms and does transformation for different channels. And that's sort of the interim strategy you're going to want to use.
