Unfortumately, this may not be not an option for me. I am constrained by the policies of the corporation for which I'm working. At present 5.1.0-GA is the only platform they'll support, and they WILL NOT ever support 6.x.x, but there is some talk of supporting in the not-too-distant future 7.x.x. I will try to press and see if this may be pushed forward.
