If you're trying to access a Session bus, you need some way to discover the 
session bus address.  Using the System bus does not have this issue (it has 
others:)

There is an apache module that will let you set env vars, but I doubt it 
would be able to access the data you need (the session bus address).  In my 
script, I read the current address from a file and stuff that into the env 
var.  Certainly less than ideal, but workable for now (I've only recently 
started using Session buses ).
