Keep in mind that the Kindle uses Adobe's Reader Mobile SDK (sans ePub, sans ADEPT) for PDF rendering. So they can do anything that any of the other ereaders can do. Sony's implementation seems particularly feature-rich.
The
KDK Developer Guidelines state that:
Quote:
Developer Guidelines
Voice over IP functionality, advertising, offensive materials, collection of customer information without express customer knowledge and consent, or usage of the Amazon or Kindle brand in any way are not allowed. In addition, active content must meet all Amazon technical requirements, not be a generic reader, and not contain malicious code.
We will work to refine the above guidelines throughout the beta.

(emphasis added)
Not sure if that means 3rd party PDF or epub reading apps are prohibited.
