Regulating NRAs - which is best?

There's some interesting literature on the formation of UK super-regulator, Ofcom - though most of it in the 2005 internal report designed to forestall any National Audit Office critique in 2006. 
Obviously the United States NRA, the FCC is not the only NRA game in town, even if it is the biggest. The awesomely large FCC International Bureau does have a small sub-function which almost seems an afterthought on how international regulation can affect the FCC-US markets (as opposed to vice versa!). To me, the function that works better is OPP in its international dimension, and it's here that good work is produced.
Internationally, ITU have been contributing to a Promoting Broadband initiative.
