The context of my question is now R2, the new release of Dynamics AX for Retail - POS:-

Any answer to the question whether we can customize POS extensively and bring some standard AX functionality to POS which is .Net client. I'm interested to develop it extensively, e.g. to bring in the functionality for Sales quotation before a sales order is generated. The limited Interfaces for POS provided by Microsoft does not seem to enable me to do so. Any clue or pointer or any reference to the person who is doing such sort of heavy customizations to Retail POS?
