Hi,
The tcp-nio protocol is labeled as experimental so there might be surprises
with that as opposed to tcp.
The udp protocol depends on multicast which is likely to be broken in real
world networks as almost nothing depends on it.
I observed the pinging of the next higher port in my testing, here in the
default tcp.xml it is configured
to ping 7800 and 7801

After having moved to the tcp-nio protocol stack, and manually adjusting the
port numbers for each instance, I could finally get it to work.
I am still having announces that some ports are connection refused but these
are not the ports I configured but the port +1... is that classical?
Is there an advice for us to use UDP? I would have expected this to be worry
free on a simple desktop when looking at localhost... but well.
Sorry Paul but we are not yet JGroups experts ourself, I mostly used
TCP for tests. You might get more valuable informations from JGroups
mailing list.

You could enable debug log to see if cluster members talk to each
others. See
http://extensions.xwiki.org/xwiki/bin/view/Extension/Observation+Module+Remote#HDebugging.
I did this: into WEB-INF/classes/logback.xml, added:
<!-- remote observation detailed logging -->
<logger name="org.xwiki.observation.remote" level="trace"/>
<logger name="org.jgroups" level="trace"/>
and on the side of the sender I did get the nice following debug line:
2012-07-06 17:02:28,122
[http://hoplahup.homeip.net/xwiki/bin/saveandcontinue/Main/Test3] DEBUG
.o.r.i.j.JGroupsNetworkAdapter - Send JGroups remote event [event:
[org.xwiki.bridge.event.DocumentUpdatedEvent@b6362ec], source:
[{origdoclanguage=, origdocversion=8.1, docversion=9.1, doclanguage=,
docname=name = [Test3], type = [DOCUMENT], parent = [name = [Main], type =
[SPACE], parent = [name = [xwiki], type = [WIKI], parent = [null]]]}], data:
[{contextuser=XWiki.adminPolx, contextwiki=xwiki}]]
But not much more.
However, I do not seem to see a connection to the other "node".

You could check with JMX to see the status of the cluster, see

Vincent, that seems like something very useful but how do you read the
connected clients there?
Which attribute would list this?
I see neither on your screenshot or my jconsole.
