I know VW has a C interface now, so it is theoretically possible to develop
a python binding (hunch.net seems down as of now, but John Langford wrote
about it on the blog).
However, memory structures possibly don't fit properly with numpy arrays
(which are the recommended API choice for sklearn I believe), so it could
become a bit hard.
Also I would be inclined to think it could hurt VW performance to feed him
with a different pattern of data input as the VW folks have passed a good
amount of effort in optimizing I/Os I believe.
