However it is not restricted to just that role, it can act as a publisher device and send data to an open data service such as Pachube, and it can act as a web connected I/O device, which subscribes to a Pachube data feed and acts according to the data received from that feed - for example setting its I/O, updating a display or controlling some actuator device. | However it is not restricted to just that role, it can act as a publisher device and send data to an intermediary open data service such as Pachube, and it can act as a web connected I/O device, which subscribes to a Pachube data feed and acts according to the data received from that feed - for example setting its I/O, updating a display or controlling some actuator device. | ||
By using Pachube's API as a smart intermediary, much of the burden of serving an interractive webpage is eliminated from the Nanode. | By using Pachube's API as a smart intermediary, much of the burden of serving an interractive webpage is eliminated from the Nanode. | ||

A final application, uses an interpreted language called [http://bitlash.net/wiki/start Bitlash] which allows scripts to be written and stored in EEprom on the microcontroller or on an external SD card. We are developing a Telnet aopplication which would allow a Nanode running bitlash to be remotely reconfigured to run a different script. | A final application, uses an interpreted language called [http://bitlash.net/wiki/start Bitlash] which allows scripts to be written and stored in EEprom on the microcontroller or on an external SD card.

Nanode has a lot in common with the Tuxgraphics Web Server - in fact the Tuxgraphics TCP/IP stack was ported to Arduino, and thence onto Nanode. Here's an [http://tuxgraphics.org/electronics/200905/embedded-tcp-ip-stack.shtml article] with a lot of the background information to how the stack works and how it serves small web pages efficiently. | Nanode has a lot in common with the Tuxgraphics Web Server - in fact the Tuxgraphics TCP/IP stack was ported to Arduino, and thence onto Nanode. | ||
