Oh, this is very clever. It's a mozilla-based server-side DOM+Javascript implementation which mediates between a client browser and a backend http server. So you can do DOM manipulation and Javascript processing on the server, the client, or both. It supports connecting to local and remote web services so you can leverage your own backend or an external third-party site. And you can manipulate that DOM before sending the data back to your client! Interesting, very interesting. It sounds promising as a way to tightly couple your server processing to your client display. Transparently calling between the server and the client is an interesting approach. My big concern is adding what seems like just another layer in your server stack. Aptana seems to think that Jaxer can replace other server-side technologies like PHP or RoR, but I'm not convinced. I also think that tightly interweaving your server and client could generate some massively ugly code and nearly unmaintainable codebases. Proper separation of concerns could be very tricky. Now if they'll just get it running on Linux maybe I can check it out.
