I code in Scala for some time now. Love this language! Though I think that Node.JS is something different and has different purpose(yet to be discovered). Scala as any language that runs on JVM, doesn't completely support Non-Blocking IO(this should be fixed in Java 7 though).

"JVM, doesn't completely support Non-Blocking IO"

Isn't java.nio supposed to provide non-blocking IO (at least for socket)?

Yeah, for sockets java.nio does that just fine, not for files. Of course, it's an improvement over plain java.io but still it's not non-blocking.

Actually, given improvements in threading, NIO doesn't give faster socket throughput in typical many-connection servers. See:
