I like Google Earth, too, but there are some serious problems. Processes seem to be terminated arbitrarily, and far too soon. Interprocess communication is too difficult. I can’t seem to execute a JOIN successfully. Forking new processes is fun, but time consuming and expensive. Most independent agents are severely lacking in intelligence. System management is byzantine and security is non-existent, I mean, anyone can kill a process with almost no effort! I can’t wait for Google Heaven, though. If it’s anything close to what’s advertised, it should make up for all the crap we have to go through with Google Earth.
