Then it should be good,Until some body comes and ask from us.

Is the GUI specific for IBM, if not then I know google is planning to 
support the IPv6 and the gui should be at par with other available 
stack(AMI/ATEN).

Please ping Victor Hu from IBM(HPC), I have seen the AMI as well as the 
SuperMicro(ATEN) stack, they are supporting it.
