I don't know exactly, since I don't know how this works on Windows. What 
is the "fd" you pass to the daemon's --print-addr-fd function? Is it a 
pipe or a socket or what is it? On UNIX autolaunch does a fork/exec, 
what does it do on Windows?

A larger question is why do we need autolaunch on Windows - autolaunch 
is used in two cases on UNIX, 1) ssh to a remote machine and displaying 
an X app on the local machine 2) logging in as another user and 
displaying an X app on this user's display. I don't know that either 
thing really comes up in the Windows case.

How does the bus get found in the session normally? There are lots of 
single-instance apps in Windows, we should be single-instance probably 
using a similar mechanism. The DBUS_SESSION_BUS_ADDRESS env variable 
doesn't seem very good on Windows since we have no way to arrange for it 
to be set for every process in the session afaik, and it would require 
logout in any case.

Again, don't emulate UNIX. Do what makes sense on Windows natively... 
the command line options, config files, bus addresses, etc. can be 
different on Windows when the UNIX versions don't make sense.
