Nice script, I just a use this little identifier I wrote up for nIRC.

alias disnick {
  if (!$isid) halt
  if (!$2) {
    if ($cnick($1)) return  $+ $cnick($1).color $+ $1 $+ 
    else return  $+ $cnick(*).color $+ $1 $+ 
  }
  if ($left($nick($2,$1).pnick,1) != $left($1,1)) return  $+ $nick($2,$1).color $+ $left($nick($2,$1).pnick,1) $+ $1 $+ 
  else return  $+ $nick($2,$1).color $+  $+ $1 $+ 
}

Use: $disnick($nick,$chan) $chan is optional.
It returns the nick prefixed with their highest mode, it will also be colored according to your nick color setup.

Edit: Hmm, the control+* chars arent showing up :/

I rate it a 7.
