Well, if you will join me in creating that package right now then it
will no longer be a pipe dream: I will help you and it will happen
(hopefully others will join us)! I really don't think we have mutually
exclusive goals. Otherwise I will likely sit on the sidelines and
build my personal collection of random data analysis code...
