+1 for Gregg's view on docs and +1 for Gregg's view on what online books
should do :)

As for the topic, i'd like to start to fill that gap. I'm not a pro in
concurrency, but aim to be, so taking my hands on filling this gap seems
like very challenging for me and very exciting to work on. This is so much
better than writing code for wastebin.

I'd like to suggest everyone who is ready to volunteer their time and
experience to help. We can start from porting the examples to Java, and end
up with a book that will be both innovative and exceptionally useful.

I can provide some resources like hosting and maintenance, can do some
coding, can do some writing, what i can't provide is a lot of experience
that is a valuable asset in such task.

I'm also not imply pretending to lead this process, i think the person with
broad enough vision and experience should.
