  The advent of new electron accelerators with few-GeV beam energies makes the
(e,e'p) reaction a promising tool for investigating new aspects of the
electromagnetic interaction. To this purpose it is crucial to set the scale of
Final-State Interactions (FSI) at high ejectile energies. We have analyzed the
constraints which allow for a meaningful generalization to (e,e'p) of the
Glauber method used in elastic (p,p) scattering. The FSI dominance at large
deflection angles produces in the distributions a universal behaviour
resembling the coherent diffractive scattering between the ejected proton and
the (residual) nucleus. It is argued that the comparison between (e,e'p) and
(p,p), when a meaningful one, may represent a convenient tool to disentangle
(exotic) effects due to FSI from those related to the (hard) electromagnetic
vertex.
