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

We are currently using javaspaces (the Sun outrigger implementation), to coordinate loosely coupled processes. The idea behind it is compelling, and the API is very simple. The actual implementation has been a problem. It's built on Jini, so 5 or 6 processes are required to bring up a space. And, at least in Sun's implementation, there is no way to have it communicate over specific ports, which makes firewalls a bit of a pain.

The other issue that we have run into is that there is no implied ordering in the space. So if you put 5 objects in, and your template on the read/take matches all 5, it is unspecified which one you will get. Depending on the application, this may or may not be an issue.
