Here is the link to SUN's new RFID website:

http://wwws.sun.com/software/solutions/auto_id

The 'Architecture' document contained there indicates how much work they had to
do in order to accommodate reading large numbers of tags in a short span of
time.  One important aspect of this new architecture is that the Savant servers
are really high-powered embedded systems that are deployed near the RFID
readers.    

One implication of this is that what use to be a J2EE application that was
located completely in the backend infrastructure is now an application that is
partially located in the backend infrastructure and partially distributed
throughout the facility in embedded devices.

The process of how the J2EE community is going to accommodate this new class of
application is one of the things that is most interesting to me.

I am looking forward to seeing what kind of architecture ideas you are
sketching out.

It has been my experience that one of the challenges encountered (usually
before the device integration challenge is encountered) is in figuring out how
to even begin discussing this new class of application at the business case
level.  This is completely new territory for most people and, for the most
part, they do not even know how where to start because there is no past
experience to guide them.  One the reasons that this group has been working to
figure out what the best-practice patterns in this space are is to help out
with this problem



I am beginning to think that it would be an interesting idea to partner with a
J2EE community like 'The Server Side' to set up a pilot program where
developers can start experimenting with these new technologies.  I think that
us Embedded Java developers would be able to put together some experimental
hardware system specs and embedded software if we could find some J2EE-based
organizations who would be willing to deploy them and start experimenting with
the J2EE code needed to accommodate them.
