you could imagine also to list groups and script name in a text file.

example :
group1;my script for group1.kix
group2;my script for group2.kix
group3;my script for group3.kix

then you read this file and test for each line if user is in group
(comment a line with a ";" )
Code:
$handle=freefilehandle()
if open($handle, "ListGroup.txt",2)=0
  $line=Readline($handle)
  while not @error
    $line=trim($line)
    if left($line,1) <> ";"
      $array=split($line, ";" )
      $group = $array[0]
      $scriptname = $array[1]
      if InGroup($group)
        if exist($scriptname)
          call $scriptname
        endif
      endif
    endif
    $line=Readline($handle)
  loop
  $=close($handle)
endif


This code is not very secured and I haven't tested it but it could be a good start.

For performances, it is important to know the average of groups people are in and the average of groups associated with a script.
