RE: [JXTA discuss] JXTA applications

That's a great platform for a "JXTA appliance". What
sort of power requirements do they need? What about
smaller footprint devices that could run on a battery
such as motes, cell phones, GPS devices, RFID tag
readers? These could be deployed along with the even
smaller devices for aggregation, provisioning,
gateway, etc. 

One example would be a mesh network of sensor devices
(low power) that know the location of other sensors
relative to their own location. A GPS device, which
has more power requirements, but you only need one,
can be hooked into that network to determine the "real
world" locations of these devices. A network of these
GPS systems can then feed the backbone to control
centers, other GPS stations, etc. for situational
awareness applications. The security and organization
of these networks could be handled by JXTA.

Another would be motes that are RFID tag readers.
These could be used to reduce the cost of deploying
tag readers in every location where tags are read.
Instead, you deploy low cost battery powered motes
that feed into tag readers that aggregate the data
read from the motes.

With the flexibility of JXTA and the various
footprints being developed the list goes on and on. :)
