Oh no, I certainly wouldn't suggest delaying the alpha any longer. 
Improving the autostart editor would be great, but isn't necessary for 
my nefarious plan.

Well, the autostart spec doesn't have provisions for dependencies, 
right?  So anything we'd do along those lines would be an extension to 
the spec.  I'm still not really convinced we *need* start order control; 
as I said, the only app that really needs to be started first is 
xfsettingsd, and xfce4-session does that for us.  We'd lose our 
workaround to force-load the thunar daemon (for the trash service), but 
really, I hate that workaround, and people should just stop having 
broken dbus configs and it wouldn't be a problem.

Yeah, I guess my issues with SM in part stem from how confusing it is, 
and how it makes use of archaic, often-broken protocols like ICE (well, 
arguably it's the libICE implementation that's broken, not the protocol, 
but... yeah).  In contrast, the xdg autostart mechanism is simple and 
pretty clear, and your average semi-techie can figure out how to edit 
the raw files if needed.  Figuring out what's wrong with a SM 
installation is a lot harder.
