This is getting off-topic fast: even C code can be portable (one binary per
platform) and that scheme is allowed on CRAN and used by a few packages.

It just can't be C++ for reasons that have to do with the language and
compiler. So for 'simple' Rcpp code, just ship the source.  And as R, CRAN,
Rcpp, ... are all open source that is the right play anyway.
