  Strong winds from massive stars are a topic of interest to a wide range of
astrophysical fields. In High-Mass X-ray Binaries the presence of an accreting
compact object on the one side allows to infer wind parameters from studies of
the varying properties of the emitted X-rays; but on the other side the
accretor's gravity and ionizing radiation can strongly influence the wind flow.
Based on a collaborative effort of astronomers both from the stellar wind and
the X-ray community, this presentation attempts to review our current state of
knowledge and indicate avenues for future progress.
