How about expanding $nick so $nick(#,0,i) would return the number of people idle in the channel? Hell, at that point you could (in THEORY) do $nick(#,0,i).N where N was an idle time that could be used to see how many idlers were OVER that time. This (the first half of this post) should be easy enough to figure out and implement (he said from a NON programmer POV)
