  The emission processes responsible for the observed X-rays from radio jets
are commonly believed to be non-thermal, but in any particular case, it is
unclear if synchrotron emission or one or more varieties of inverse Compton
emission predominates. We present a formulation of inverse Compton emission
from a relativistically moving jet (``IC/beaming'') which relies on radio
emitting synchrotron sources for which the energy densities in particles and
fields are comparable. We include the non-isotropic nature of inverse Compton
scattering of the relativistic electrons on photons of the cosmic microwave
background (CMB) and provide beaming parameters for a number of jets. A list of
X-ray emitting jets is given and the jets are classified on the basis of their
morphology and spectral energy distribution to determine their likely emission
process. We conclude that these jets have significant bulk relativistic
velocities on kpc scales; that higher redshift sources require less beaming
because the energy density of the CMB is significantly greater than locally;
and that for some nearby sources, synchrotron X-ray emission predominates
because the jet makes a large angle to the line of sight.
