*bump* again, but I doubt it will help...
Starglim has added extra text of his own to the spell description, without making it clear which is the actual text and which is opinion. This is a bit misleading. The line For all other purposes, it is made of moonlight simply isn't there.
The full text is just this:
Moonlight Bridge (Su):
You summon a bridge of shimmering moonlight. The 10-foot-wide span touches the ground at a point adjacent to your position. From this point it can extend in any direction for 10 feet per oracle level. The path persists until you have crossed over the bridge or for 24 hours, whichever is shorter. You may summon a moonlight bridge a number of times per day equal to your Charisma bonus. Should the bridge be attacked, treat it as a wall of force.
There is absolutely no mention of things passing through it. The Moonlight description appears to be just a description and fluff, rather than anything to do with mechanics.
So it would seem like it is to be treated as a force effect for all relevant circumstances, with the special duration (24 hours or until the Oracle 'crosses' it, whichever is shorter).
Thus the first set of rulings by cwslyclgh seem the most compelling.
