Hi,

you also have seen that a hop penalty of 10 is too high ? Can you explain your 
setup a bit more ?

I am certain that you great ideas and that you spend a lot of time on working 
with batman / meshing. However, it is somewhat difficult to review / discuss / 
adapt your work since we have a hard time understanding your concepts without 
proper explications / documentation. Would it possible for you to talk/write a 
bit more about your stuff ?

The WBMv5 is a good opportunity to chat because you get all of us in one 
place.  ;-)

Cheers,
