Hi PMCW - I am no expert but have experimented with such devises in my home. Think of these devises as very inexpensive intelligent sensors (or agents) that can measure, view, compute and report the current (real time status) back to the server.

These devises "plug" into a home LAN which also could link to a central "intelligent" server that perhaps monitors several hundreds of thousand individual LANS.

Specific applications are only limited by your imagination. I developed a home aquaponic system that controls pumps, PH sensor controls, measures temperature, sets water levels all through devises controlled by my LAN. Now my control modules are not JINI controlled devises but could be if available. In fact, JINI makes these types of applications much eaiser to install, perform data inquiries, and in fact make the devises much more intelligent.

The power of the design is to have a central server that constantly monitors these devises on a very large network. This is where the smart "intelligent" SUNW servers are used.

This is an emerging technology and the infrastructure (i.e. standard protocals) are still being developed.

The LINUX OS can now control X.10 devises. Here is a link where you can see what is being done NOW in the home with X-10 technology which just begins to harness the power of network devises.

Here is a link to an experimental aquaponic design that I set up last year (http://rainey.blueneptune.com/~eks/)

I guess it was a bit before it's time but it worked quite well.

I'll give you my layman-level understanding. JINI defines a means by which devices announce their presence on a network and describe themselves (e.g. their capabilities) sufficiently to allow communications. This happens dynamically, so it's not necessary to load device-specific drivers in advance. In essence, the devices provide their own drivers to the rest of the network as soon as they're attached.

JMHO.
