So far the standard way of making data connections in Ajax applications has been over XmlHttpRequest, which requires clients to constantly poll backend servers. Adobe is taking advantage of the opportunity to open up a solid platform capable of providing persistent connections (server push / Comet) and the AMF specification.

According to the Adobe Labs site:

Adobe is announcing plans to release source code for its server side remoting and messaging technologies under a new open source product named BlazeDS. Now, developers can easily connect to back-end distributed data and push data in real-time to Adobe® Flex™ and Adobe® Integrated Runtime (AIR) applications for more responsive rich Internet application (RIA) experiences. Previously available only as part of Adobe LiveCycle® Data Services ES software, the technologies included in BlazeDS, along with the Action Message Format (AMF) protocol specification, are being contributed to open source under the Lesser General Public License (LGPL v3) and are available immediately as public betas on Adobe Labs.
