This is true, and I believe an ordinary copyleft license (such as the
GNU General Public License) will serve him well.  In the interests of
full disclosure, the Reciprocal Public License requires developers of
modified versions to "Notify the Licensor of the availability of Source
Code to Your Extensions in a timely fashion and include in such notice a
brief description of the Extensions, the distinctive title used, and
instructions on how to acquire the Source Code and future updates."  I
would strongly recommend against using this license, as it is
burdensome, over-complex, and as a result very unpopular.

Right.  It's probably worthwhile to push this kind of discussion onto
another list (license-advice ?).
