I hope this article will grow as people read it. For now this is how I limit my pptp and yes I'm refusing to use radius.

Scar's Interface traffic limiter (Fail cake edition)

This is the script checks how much data has been used on the interface, if it is over the limit it will disable the interface.

# Interface limit for pptp

# interface you want to limit
:local interface "yourinterfacegoeshere";
# limit in mb
:local limit 30;

:local bool [/interface get $interface disabled];
:if ($bool = false) do={
  :local usage [/interface get $interface bytes];
  :local ulen [:len $usage];
  :local rx;
  :local tx;
  :local total;
  :local totalmb;

#   Mufasa's example next line:
#  :put [:pick [ /interface get $interface bytes] 0  [ :find [ /interface get interface bytes ] "/" ] ];
  :for j from=( $ulen ) to=0 do={
    :if ( [:pick $usage $j] = "/") do={
      :set rx [:pick $usage 0 $j];
      :set tx [:pick $usage ($j+1) $ulen];
    }
  }

  :set total ($rx+tx);
  :set totalmb (($total/1024)/1024);
  :log info ($interface . ": rx:" . (($rx/1024)/1024) . "mb + tx:" . (($tx/1024)/1024) . "mb = total:" . $totalmb . "mb");

  :if ($totalmb>$limit) do={
    :log info ($interface . ": is over the limit, disabling...");
    /interface set $interface disabled=yes;
  }

} else={
#  :log info ($interface . ": disabled");
}
