You know, when we have our international stereo competition, the 
projectionists can go to sleep because practically all of the entries
are mounted right.  Really, by doing all this projector adjustment, we're
probably doing our club's members a disservice.  We should align with a 
standard slide and then just leave the projector alone (except for 
focus).
Is this the consensus of projectionists here on the list?

While I agree that excessive projector adjustments are distracting (and 
painful), judicial and swift adjustments are an important part of 
projection.  The vertical adjustment must be performed by either looking 
over the glasses or through small holes cut into the top of them; any 
(small) misalignment can then be quickly corrected.  The horizontal 
adjustment, for the most part, should be used to minimize any ghosting of 
highlights in the slide; this is largely a judgement call which must be 
made quickly and decisively.  Gross errors in separtion must of course be 
corrected immediately.

The important point is that with one person on the verticals and another 
on the horizontals  these adjustments should not take longer than 1 -  2 
seconds to complete; the focus control should be operated by a third 
person.

I prefer to mount to the window,letting infinity fall where it may.  This 
ensures that nothing gets chopped off by the window, or comes through the 
window (except by design); I think  it also maximizes the perceived depth 
of the scene.   It's usually not a problem unless I was too close to 
something in a scene with infinity also present (better not project those 
:)).
