Beyond Java 2nd edition

I suppose its high time Bruce Tate beyond Java book needs a 2nd edition, I am hoping to write the newer edition :-)

I request your kind suggestions and comments for the chapters?

My ideas are around

1.) Groovy and Grails need a better objective analysis - Existing JVM languages ( JVM installation base, Java's corporate penetration and inertia to change)

2.) Success and limitations of Ruby and ROR needs to be assessed ( penetration into Java's castle )

3.) PHP as a language with a never say die attitude.( Rapid prototyping Vs waterfall model)

4.) Cloud computing and their impact, Software as a service and future,

5.) Statistical R as a tool for BI solutions - possibility of R on JVM and R for web?

6.) Google chrome OS its role in future

7.) Earlang and concurrent programming
