Yeah, I thought and mean exactly about the new packet type ("result"). Of course not ordinary exec-packet. >That actually dramatically simplifies things. Should so! I am honestly do not know why I artificially limited ability to "reroute" those packets. Possibly becase I assumed that the originator of the packet forcefully wants *exactly* that nodes to participate during the transmission? Possibly someone forcefully do not want some node to see some packets (even their sizes)? But anyway noone has any guarantees about delivery path, so why bothering? It is like SMTP: you can send email to the server via forced TLS, but after that, you have no abilities to control if TLS is used at all. -- Sergey Matveev (http://www.stargrave.org/) OpenPGP: CF60 E89A 5923 1E76 E263 6422 AE1A 8109 E498 57EF
