We are developing a parallel-computation version of R (at present for
internal use only ;-). Basically there are a number of R processes running
on several host computers. Data and functions (i.e. R objects) can be
exchanged between these in PVM-based messages. We use the *string*
representations of R objects to build the messages being send (by a
combination of calls to deparse at the sending process and parse at the
receiving process).

Therefore it would be very nice to have variable-sized string arrays in R!
