  Virtual Compton Scattering (VCS) at low transferred momenta to the proton
($t$) and sufficiently high c.m. energies ($s$) may be used to a) study
$Q^2$--dependence of leading $t$--channel exchanges and b) look for onset of
scaling behavior with increasing $Q^2$. I discuss the implications for
perturbative and nonperturbative QCD and suggest possible experiments.
