Ajax is the name
I don't know how long has this term being around, but AJAX is the name.
So... what is AJAX?...
In his essay "Ajax: A new approach to web applications" he defines it as:
- standards-based presentation using XHTML and CSS;
- dynamic display and interaction using the Document Object Model;
- data interchange and manipulation using XML and XSLT;
- asynchronous data retrieval using XMLHttpRequest;
And since article appeared in the last month... lots of people are now referring to the new term and there has been a lot of interest in using it... there is even a blog!. Even in the land of Ruby, Rails already support Ajax technologies. Matt Raible mentions a sample using Tapestry and Ajax.
