Most mobile technology is moving away from HTML toward the use of Flash. The Flash files are samller and much more robust.
Also, if your technology is going to be dynamic, you will want to learn about the mobile technology class files of program environments such as .NET and Java.
Dreamweaver can, as it does now, serve as an assembly point to bring these technologies together.
Hope this helps,
