AJAX - critical evaluation

I have recently finished an evaluation paper on AJAX enabled Webpages aiding Property managemet. Please take the time to read the paper and please post your replies.

How would you have evaluated the products differently?
What other development technologies would you have included?
How can this paper be carried on to include other issues?

Abstract—This paper analyses different AJAX development technologies. It evaluates the feasibility of one in particular in relation to developing an AJAX enabled Web application for enhancing the management of properties and property details. The core functionality needed and the issues which arise in development are also analyzed. Features of AJAX in relation to specific benefits and limitations of the application are viewed critically for recommendations.
