Now this is something really interesting: as found on Adobe Labs site, their technology codenamed Apollo is approaching Alpha status. What Apollo is – in a nutshell – is another virtual machine, similar to Java runtime or .Net framework, with few minor twists: it is multiplatform (as Java) as well as multi-language (as .Net) at the same time. Before flame wars start – I am aware that JVM is capable (more or less) to support multiple languages beyond Java and also that .Net is (more or less) capable running on non-Windows platforms (e.g. Mono project), but that is not the point. The point is what is different about the Apollo compared to JVM or CLR.
It is still Alpha so it is too early to get excited, we have no data about performance, resource requirements or real world application development experience. Positive is that both runtime as well as SDK should be free. And it is always good to have more options available 🙂
