Astral Perception vs Chameleon Suit/Infiltration, Now you see me ... Options

[ToreadorVampire]

So - the topic makes it fairly clear ... if I can get an official ruling from a dev on this then great but I'm also interested in hearing community opinion.

Simon the Stealthy is wearing a chameleon suit and is sneaking up on Paulo the Perceptive using the Infiltration skill, let's say it's in a background area where there isn't much natural/living stuff - an industrial area.

Paulo is using Astral Perception.

Does Paulo need to take the -4 penalty to his perception tests (in order to spot Simon) because of the chameleon suit? You could argue "the chameleon suit doesn't exist in astral space" but the other way you could argue "astral perception doesn't let you see through walls" so things that impede perception in the realworld™ impede it in the astral.

This is the main area of contention our group just struck. Beyond this, how about the infiltration skill? Can Paulo (with their astral perception) ignore Simon's use of the Infiltration skill? I don't believe he can but I have heard the explanation "In astral, everyone's life signs and auras are bright glowing things that show up really clearly against the background, no way you can sneak up on me!"

Now, I don't think that astral perception should be "immunity to the infiltration skill" but I've had a harder time justifying "chameleon/camoflage suits work versus astrally perceiving people".

What are the thoughts on this, and has a ruling previously been made on this that I should know about?
