I'm not a crypto expert, but presumably once you get over a certain key size, it
becomes a moot point? A cipher is either practical to break or not, which (assuming
it isn't susceptible to cryptanalysis) is based on available computing power vs key
size.
If this goes on the way everything else goes, any n-bit key (n of reasonable size)
must be secure enough that you would be better off worrying about your wife cheating
than someone reading your traffic; if someone can easily break (what is now
considered to be) a large key, there has been a development that can't be anticipated
now (such as quantum computing?).
FWIW,
Geoff
