Does the whole thing needs to be retrained everytime you want to add more data
or can it just be updated.

One of the problems with using Haar features for face recognition now, is
because you also need a large training set, and you can't easily add more data
to the cascade, in other words it has to be retrained from scratch everytime,
which is a big problem.

Also bear in mind this is supervised learning, so there is a reliable input
from people to tell what is right and wrong. So only correct data is added to
the classifier/cascade.

Thanks for the idea though, would be interesting to have a look at that at some
