How do you define "light path length"? Do you just look at the amount of
time the light took to get from one end to the other as measured by your
own clocks, and then multiply by c? If so, then if the rulers don't
appear to shrink depending on their velocity, and if all observers agree
about simultaneity as you suggested below, then in frames other than the
ether frame, the light path length will vary depending on which
direction the light beam is moving.

No, but in SR each observer defines his time-coordinates in terms of the
readings on a set of clocks which are all at rest relative to himself,
and which have been "synchronized"based on the assumption that light
travels at the same speed in all directions (so two clocks are defined
as synchronized if a light shined at their midpoint will reach each
clock at the same time).

I don't know what you mean by "see simultaneity occur". In standard SR,
you don't "see" simultaneity, simultaneity just means that two events
are assigned the same time-coordinate in your reference frame (with the
time-coordinate of each event determined by the reading on a clock at
the same spatial location as the event, with all the clocks at rest
relative to the observer and synchronized by the method I mentioned
above). If you are talking about when the light from two events reaches
you, that is a separate issue from simultaneity in SR--the light from
two simultaneous events won't reach you at the same time unless the two
events are both the same distance from you.
