GIN was inspired by tequila from jcfontain but i wanted a distributed system with no dedicated server and faster performance. * gin uses udp packets from either Tnm by Juergen Schoenwaelder this is currently broken as Tnm Udp Stuff seems to have been turned inside out. or * TclUDP from Pat Thoyts Multicast Adresses are used for sending to multiple addresses. in my application sensors of any kind send their data on a multicast channel. Ackknowledges of commands ( to any actor ) are repeated on a multicast channel. Unicast Adresses for sending to a single instance actor. in my Applikation Actors of any kind get their data from a unicast channel.
