well... we didn't come to tune up the tools for continuous labels yet
but they simply might work (I meant all kinds of custom classifiers in
mvpa.clf.classifier), but there is one basic classifier which can do
regression now (ie effectively do continuous label classification if I
get it right) -- SVMBase with appropriate parameter... just see help for
its __init__, it is pretty much just an adapter (to fit our
schema) around libsvm's python binding.

It would be great if you share how far you get with that one.
