Might be wrong, but anything "auto-magic" sounds like not a very good
idea, saves time probably in the short term, but I''m not sure that's
what you want...
Notwithstanding the dangers, I suspect it is an idea
who's time has come - for security as well. It is
what happens on the Mac OSX, and I for one am jealous
of that feature.
(Whether the Mac also introduces other problems in
this way is an open question ...)
