Side question: are "SW guys" satisfied with the tools/languages available for multi-core development? I really like Intel's Threading Building Blocks for multicore programming in C++ and I really like Clojures take on time and concurrency, but overall, I feel language support is very limited and library support doesn't mesh as well with the languages as hoped. I would like to see a practical dataflow-centric language.
