So arcane sight - lets you know the number and location of all auras within your vision's range - Does it work through arcane eye?
I assume it does - so the sensor is noticed by an int check (any creature with a 12 or higher int can make a int check (DC 20) to notice the censor - it can be dispelled - would the dispel magic being cast show up as an aura before the dispel hit? Or does the act of casting produce an aura before the spell is actually cast - ignore the spellcraft rules for a moment (for this discussion) and assume that there is cover and normally wouldn't be detectable if the person was standing in the room (sans arcane sight).
Arcane sight (based on the spell description) ignores cover and isn't subject to the 'lead, stone, etc.' restrictions - it's 'all auras, within 120 feet' So based on that does the act of casting a spell produce an aura before the spell is actually cast?
Ok - assume the room in question has numerous NPCs, equipment, running spells and such - and all of them can turn gaseous as a SU ability - would a followup look at the room show any auras if all the creatures were gaseous?
Does the 'gaseous form' show an aura as an SU ability? Would the equipment/spells active/etc. still show in the gaseous state?
Hoping to see some suggestions from the community before my next session on Tuesday - while this is hyper specific due to the permanent arcane sight spell I expect to have more odd interactions like this for the next several months as we wrap up our RotRL campaign.

First, arcane sight is limited by cover and so on. It say explicitly "The effect is similar to that of a detect magic spell, but arcane sight does not require concentration and discerns aura location and power more quickly.", so it inherit all the limitations of detect magic that aren't specifically changed.
That limitation is even reiterated: "You know the location and power of all magical auras within your sight". You don't see what is outside your sight, i.e. behind cover.
Second, no casting a spell don't produce an aura before the spell is actually cast.
Only spells, spell like abilities and magic items have an aura, so a SU ability to become gaseous don't leave any aura. The other auras from spells and items are present even if a creature become gaseous.
Lat: Arcane eye don't say that you get to use other spells trough it, so, no, Arcane sight don't work. it has a range of120' from you, not from another spell.
3) "does the act of casting a spell produce an aura before the spell is actually cast?"
The act of casting =/= before cast. An aura is produced when the spell starts to be cast. One can still use Spellcraft to determine what spell is being cast even if it is interrupted or the spell fails.
4) Gaseous form has interesting interaction with magic items and spells- they may become ineffective or moot. Arcane Sight will still allow you to see their auras.
Eh - I disagree on arcane sight only because it has specific language about things you can do if you actually have line of sight - being 3rd level and not a cantrip I ruled otherwise - it is what it is at this point - but I do appreciate your thoughts on it.
Your number 3 - well yes you can make a spellcraft but that's based on the 'casting' as you don't need detect magic up to make that check - hrmmm more to ponder.
#4 - I like that and I think I'll run with it - detect magic in a room with 90+ auras is a pain the butt.

What detect magic detect:
Functioning spell (spell level)
Magic item (caster level)
A spell is not functioning while it is cast.
1) I would say Arcane sight works through Arcane Eye. Relavent part of Arcane Eye:
It sees exactly as you would see if you were there.
It is a scrying spell, so you are right as "A scrying spell creates an invisible magical sensor that sends you information. Unless noted otherwise, the sensor has the same powers of sensory acuity that you possess. This level of acuity includes any spells or effects that target you, but not spells or effects that emanate from you."

I (admit I could be wrong) thought that Arcane Eye having a target of 'you' meant it would work with a sensor.... I wasn't sure what 'emanate from you' quite meant but I figured perhaps like implosion or something goofy like that -

What spell are emanations is in the spell description:
Detect Magic
...
Area cone-shaped emanation
An emanation spell functions like a burst spell, except that the effect continues to radiate from the point of origin for the duration of the spell. Most emanations are cones or spheres.
Arcane sight as no area line in the spell description, it is a power granted to the caster sight.
Detect magic instead is more similar to a radar search, you emit some kind of magical wave that bounce on the target and send back information, or in game terms, it is an emanation from the caster position that give him information.
