Smartlinks: usable with Astral Perception?, how far does the interface go? Options

[shadow_scholar]

Maybe this has been brought up before, and if so, my apologies, but I was asked to take this debate to a separate place, so I have.

After a story was told in another thread about how a player used a Smartlink while Astrally Perceiving I immediately thought to myself how, as a GM, I wouldn't allow it. I personally see it this way (no pun intended), Astral Perception is not something dependent upon the eyes, it is more of a sense that is attuned to the fabric of magic, or the Astral Plane, if you will. If Astral Perception were dependent upon sight then blind people wouldn't be able to do it, but according to the SRComp Blindness becomes something like a 2 pt Flaw if the character has Astral Perception, leading me to believe that said character would still be able to Astrally Perceive despite being blind, which leads me to further believe that Astral Perception is not dependent upon physical sight, therefore cyberware that depends upon physical sight to function would not work (as I see it, a Smartlink depends upon a visual crosshair or dot put up in your field of vision to indicate where the gun is pointed, therefore it depends upon physical sight).

Your thoughts?
