Some answers,

a) Mahout is not ready for use in applications that will kill people if they

b) if you have a situation where you have training examples that you have
classified and labeled, then Mahout online classifiers may help.

c) if you have data that is not sparse, then Mahout's online learners will
probably work reasonably well, but you will need to use them differently
from the way that most people currently use them.  These learners were
designed with very sparse data in mind.
