Views and anycast serve different, although sometimes similar or
overlapping, functions. (Which you know very well, Eddy.)
Think we've gone down the path enough for people to understand at
least some of anycast's pros & cons. If anyone here would like a
compare/contrast on views vs. anycast, let us know and we'll discuss.
But not tonight. It's late, and I wouldn't want to interrupt the
flame-fest with actual operational content. :)
