      <abstract>In previous papers, we used abstract potential
      theory, as developed by Fuglede and Ohtsuka, to a systematic
      treatment of rendezvous numbers. We considered Chebyshev
      constants and energies as two variable set functions, and
      introduced a modified notion of rendezvous intervals which
      proved to be rather nicely behaved even for only lower
      semicontinuous kernels or for not necessarily compact metric
      spaces. \par Here we study the rendezvous and average numbers
      of possibly infinite dimensional normed spaces. It turns out
      that very general existence and uniqueness results hold for
      the modified rendezvous numbers in \emph {all} Banach spaces.
      We also observe the connections of these magical numbers to
      Chebyshev constants, Chebyshev radius and entropy. Applying
      the developed notions with the available methods we calculate
      the rendezvous numbers or rendezvous intervals of certain
      concrete Banach spaces. In particular, a satisfactory
      description of the case of $L_p$ spaces is obtained for all
      $p &gt; 0$.</abstract>
