XBee Internet Gateway
From Robert Faludi's Blog
XIG 1.3.0 includes several groundbreaking features. First there’s a new I/O Sample mode. Starting today, an XBee radio can squirt sensor information directly into the cloud with no external microcontroller or special configuration needed. There’s also a push feature that feeds serial information down to a remote XBee from the cloud. Again, no special configuration is needed. The XIG takes care of all the complicated stuff!
