LQ is calculated from hello-messages only. They should be realtively 
small. Thomas suggested to increase the hello-paket-size to a fixed 
amount. This may be well worth a try, but is a dirty trick.

Yes, that was my intention, too.

No doubt about that. But that is only a solution for a few 'enlighted' 
individuals ;-)
