  I present a brief review of the properties of jets from X-ray binaries,
highlighting the disk-jet connection, in which there are strong correlations
between X-ray and radio power for black holes and for neutron star in low/hard
spectral states, and reduced emission in soft states. I discuss how some of the
new "deviant" black hole systems which follow the relation normally found for
neutron stars might fit into such a picture. I close by highlighting a few open
questions which might be best addressed with soft gamma-ray observations.
