Query: Nice theory, no practice!

You know, this is a great idea/science project...but wait, it does not work...Examples don't compile, classes are not found, the technology is immature and the people on the sun archives for Javaspace are unable to get this stuff working too. Um, This reminds me of the Rome and Gehani Concurrent C and Concurrent C++ projects... great ideas, bad execution!
