I'm continuing previewing some of the features that GridGain team is working for upcoming release. One of them is support for RESTful applications. Basically, that's how you could, for example, invoke a grid task from your RESTful web application by pointing to this URL:

http://www.myhost.com:7080/gridgain/taskid=mytaskid&arg=myarg&timeout=5000

This will return XML document back with execution results which can be easily parsed by JavaScript in a usual Ajax way. That's it - you basically pass task ID, and optional argument and timeout and that's all it takes to execute a grid task. You can develop, test and debug your grid task as usual in any preferred Java IDE with all the productivity features that GridGain provides such as transparent deployment, our simple APIs or peer-to-peer class loading.

Note that this is exactly the same way as you would use, for example, Google Charts. Now, I don't know of any other grid computing framework that can get your Web 2.0 grid enabled easier than that!
