Trigger LAN connected nodes to update site on content publish.

When I post from one of my two devices on the same LAN, the other device does not automatically update in a timely fashion. I think that when I post on ZeroTalk, for instance, that my other device needs to update at least that one site so then I don't risk overwriting my posts from the first device with the second device.

No files, tests, or entry points are named. Start by locating the ZeroTalk content-publish flow and the LAN-connected peer update mechanism, then verify that publishing on one device causes the other device to update that site without risking post overwrites.
