Anyone using JavaSpaces technology?

Are there real practical applications of JavaSpaces technology and how exactly is it implemented?

We are currently using javaspaces (a Sun outrigger implementation) to coordinate loosely coupled processes. The idea behind it is convincing, and the API is very simple. Real implementation was a problem. It is built on Jini, so it takes 5 or 6 processes to create space. And, at least in Sun's implementation, there is no way to contact it through certain ports, which makes firewalls a little sick.

Another problem we are facing is that there is no implied ordering in space. So, if you placed 5 objects, and your read / entry pattern matches all 5, it is not indicated which one you will get. Depending on the application, this may or may not be a problem.

GigaSpaces is a mature version of JavaSpaces. It is widely used in financial applications that persist in silence.

As for the implementation, it is basically a transactional database of objects on top of Jini . Requests are similar to db4o.
