I am not quite sure how nlinks and tlink work. tLink seems to work with 
a vector that is not related to the current link vector but to absolute 
x/y, maybe nLink is what I need? but nlinks do not work for me at all, 
or are they no real links or is this a bug?
tLink with a vector 1/1 seems to be the same as the plain link message. 
correct? and there seems to be no difference between a tLink 1/1 and a 
tLink 2/2?

I tried to use tLink to get global damping, but I am not sure how to do 
this (attached patch..)
