oh, being the first mover is the hardest part. Finding the right
solution is a hard, it is blind Brownian motion in untested waters. Once
good solutions have been found and once they have been integrated
upstream, an architecture 'only' has to follow straight through the
example. (which is _still_ far from trivial, but it certainly doesnt
take years.)
