To recap what i understand until now:
You want to include code, that presents itself as a service, and 
provides telemetry about a vm.

If thats the case no objections. I like the idea of more telemetry. JMX 
is implemented with remoting. So if we divide the problem, whe have the 
telemetry hooks into the jini kernel, and the transport.

JMX can have all kind of transports, so if you model it a bit like 
MBeans we can later add a jini based JMX agent to it. Currently i have 
RMI based JMX transports in use, and i don't like the firewall issues 
with RMI. I would be very nice, if there is a service for every VM where 
you can get your JMX data from.

And if you export all the MBean look-a-likes through a central method, 
you can cook whatever security model you like there.

Where do you expect you want to amend the jini apis?
