IBM tries ARM-style Licensing of PPC Processors

[billt]

This should have happened about 10 years ago......I'm thinking it's too little, too late, to be of any consequence.

Interesting. But how "new" is this, really?

Did PA Semi not get a license?
Do AMCC not license it?
Did Xilinx not license it?
Nintendo, Sony, Microsoft?

I'm not sure how this new thing differs from the old thing.
