From version 1.12.26 the muticast channel interface is available. Also a new UDP interface is available.
With the multicast channel interface one can set up groups of Level II nodes that share a common channel for events. Much like a bus like CAN. Frames can be encrypted using AES128, AES192 or AES256.
With the new UDP interface one can set up a receiving interface and several sending interfaces which send UDP datagrams to remote nodes. Frames can be encrypted using AES128, AES192 or AES256.
The settings for the multicast channel interface is here http://www.vscp.org/docs/vscpd/doku.php?id=configuring_the_vscp_daemon#multicast_channel_interface
The settings for the UDP interface is here http://www.vscp.org/docs/vscpd/doku.php?id=configuring_the_vscp_daemon#udp_interface
The encryption key are under the <security> tag.
Some sample code can be found in the source tree under test/multicast and tests/udp. Not more documentation at the moment I am afraid but I work on that.
Well there are probably some bugs left…
