But getting a (process-) "private" key, and then using it in a non-private
manner is strictly against my style and image as programmer :-)

I now strongly cosider having the make file hunt down an unused
key, and save it in a configuration file. Override in an environment
variable isn't a bad idea at all; this would allow for multiple games
(Good on very large, very game-oriented systems, i.e. universitys :-)

Happy hacking !
