Now, I've implemented a tiny jabber server in my current builds and am
looking into javascript based chat servers that I could incorporate
into the introductory web page, which could be used for notices of
this sort, and jabber users could also merely subscribe to notices
from the router so that they get chat notices when something is going
wrong - "upgrade needed", "we are under a syn attack", "Earthquake",
"out of memory", etc.  I haven't found a lightweight version of
sendxmpp yet, and have never been fond of centralized chat services in
the first place (the venerable "talk" protocol has no ipv6
implementation, I note) , so perhaps there's a better standard or
system I can use that is more aggressively p2p/distributed? I have
seen chat demonstrated over ccnx, but don't know anything
about the implementation.

ejabberd is NOT lightweight but supports muc and other services.

ejabberd is probably a bit extreme for this unless you want to add more services, but I think simple broadcasts could actually be done via the Bonjour variant of XMPP (http://xmpp.org/extensions/xep-0174.html). I've no idea if a command-line client exists for that, though, and my attempts to send a basic message using netcat and Empathy failed badly. Maybe I need to publish more services with Avahi?


There is also the possibility of a lightweight email tool or the
winpopup utility for samba.


Winpopup might work, but is generally disabled on the Windows side these days (since SP2?) thanks to Messenger service spam.
