Making RIAs Accessible

My topic suggestion for Spring <br /> has been accepted. On June 3rd, I’ll be presenting the following:

Topic: Making RIAs Accessible
Description: Rich Internet Applications offer the site visitor a more interactive, engaging experience. But can this richness be conveyed to a user of assistive technologies, and how?
This session will differentiate between DOM-based (AJAX) and Plugin-based (Flash/Flex) RIAs in terms of navigation and notification of changes taking place. We will look at current and proposed best practices and techniques.
