Sounds promising ! I would just have a reserve about using Java as main language : it's always been a nightmare to get a working version of JRE. There's a lot of versions and implementations depending upon the running OS. And it's really heavy RAM consuming, even for an 'hello world'. >From my point of view, it doesn't really seems to be a wise choice. A modern language like Go, Python, Ruby, etc ... could have been far more future-proof. Best regards, Julien Escario
