Re: How to write a "proper" math document
No, David pointed out that in a previous iteration of Wolfram's deployable content initiative (which he didn't name, but was in fact .nbp, processed through the "Publish for Player" mechanism on the web), only Manipulates were supported. That was our stated policy for .nbp, although, in fact, it always worked with a large class of Dynamics generally. That is no longer true for .cdf files. CDF supports Dynamic and DynamicModule as well as Manipulates (although you'll find the marketing materials still emphasize the use of Manipulate...and for good reason since it is so easy to generate interfaces using it).

Yes, "CDF" has a nice analogy to "PDF", but so what.
