Hmmm. I'm trying to figure out whether the UK qualifies as more "far flung" 
than NZ. I puzzle that one out and let you know.

SFNs might not be the lowest cost approach. IMO, a cheaper way to do this might 
be to place two or three towers on tall hilltops, at widely different azimuths 
from downtown, in a network of translators. I don't see how NZ could possibly 
have a problem with spectrum availability, being the "far flung" island it is. 
So there should be no reason to deal with the downsides of SFNs.
