No, but I did cover some of the points before.  This time I thought I would
reply specifically to the points raised by David a few months ago.

http://stackoverflow.com/questions/603785/environment-variables-in-mac-os-x/4567308#4567308
lists the external possibilities.  Inside an app I guess you can do setenv() if you want.  Also maybe
X11 apps have a method like those to be found in KDE, where a utility looks to see if another utility
is already running and, if it is not, starts it.  Kdeinit4, klauncher4 and kded4 do that sort of thing.
