[Cluster-tech] spider's DE length

Hi Dirk,

I understand your rant. The whole thing has grown, and almost fell out 
of control. I will suggest N1MM and others to change the way they 
identify these robot spots.

Those robots spots are not meant to leak into the dx cluster network. 
That would be a nightmare. That is why we are looking for a safe way to 
isolate those spots from the rest of the dx cluster network.

73,

Felipe
