Recent observations of GRS 1915+105 and GRO J1655+40 reveal superluminalmotions in Galactic sources. This letter examines the physical conditionswithin these Galactic sources, their interaction with their environment, theirpossible formation, and contrasts them with their extragalactic counterparts.In particular, e$^{+}$-e$^{-}$ and e-p jets are contrasted, constraints onparticle acceleration in the jets are imposed using X-ray and radioobservations, the $\gamma$-ray flux from e$^+$-e$^-$ jets expected at EGRETenergies and the flux in infrared lines from an e-p jet are estimated. It isalso suggested that these sources may exhibit low frequency radio lobesextending up to several hundred parsecs in size, strong, soft X-ray absorptionduring the birth of the radio components and emission line strengthsanti-correlated with the X-ray flux. The implications for other X-raytransients are briefly discussed.Comment: 10 pages, Tex fil
