Oracle and Prosyst team up

Here's a quote:

 When it comes to connected devices, there’s
 still plenty of debate over the right 
 operating system, the correct protocols 
 for sending data and even the basics of 
 where processing will take place — on 
 premise or in the cloud.

 This might seem esoteric, but if you’re 
 waiting for your phone to unlock your 
 front door, that round trip to the cloud 
 or a fat OS isn’t going to win accolades
 if you’re waiting in the rain. With all 
 of this in mind, Oracle and Freescale 
 have teamed up to offer an appliance 
 and a Java-based software stack for the 
 internet of things.
