Modify to only display when being looked at, and at certain distance?

How could I modify the following, so the ring is only shown below the player if player is <500 units away, and in the other player's crosshair?

[lua]
local CircleMat = Material( "SGM/playercircle" )

hook.Add( "PrePlayerDraw", "PlayerRings", function( ply )

------------------------------------
local radius = 35
------------------------------------

local trace = {}
trace.start = ply:GetPos() + Vector(0,0,50)
trace.endpos = trace.start + Vector(0,0,-300)
trace.filter = ply
local tr = util.TraceLine( trace )
local color = table.Copy( team.GetColor( ply:Team() ) )
color.a = 170

if !tr.HitWorld then
tr.HitPos = ply:GetPos()
end
render.SetMaterial( CircleMat )
render.DrawQuadEasy( tr.HitPos + tr.HitNormal, tr.HitNormal, radius, radius, color )
end )
[/lua]

Thats all you need, and a brain.

Thank you. Exactly what I was looking for.
