insertion of new commands and command pipelining. There are also a bunch of new commands for network access (using Rime): ping, data collection, packet sniffing, sending shell commands across the network, and testing the single-hop throughput to neighboring nodes. Commands are also available for reading from and writing to files, reading the sensors (on the Tmote Sky platform), and accessing the power and energy consumption of the system. Dynamic loading of programs across the network is also possible, although a little untested at the moment.
