I think this would work if you users installed from a _repository_ rather
than a single zip file. So in a sense I feat it is a flaw in the setup you

You can build repositories, both local / private and visible / public, using
the drat package:  http://dirk.eddelbuettel.com/code/drat.html, also on CRAN.

Else, just have them execute a helper script you devise....
