Linux in a tiny ethernet plug

Linux Devices reports on the world’s smallest linux-running computer. Smaller than a shuttle, smaller than a pda, smaller even than an iPod mini - this computer fits entirely into an RJ-45 network jack.
Linux system squishes into Ethernet connector

German electronics company Kleinhenz is shipping a network-enabled Linux system barely larger than a standard RJ-45 Ethernet jack. “Picotux” is based on the DigiConnect ME module from NetSilicon, along with a 2.4.27 uClinux port that was probably developed by German embedded system specialist FS Forth Systeme.

While “Picotux” is not exactly Linux in the way desktop users are used to it, this is a great idea. This means that (if the jack were replaced by a wireless antenna) this could be used in minuature robots that could be controlled from across the internet.
Secure? No.
Fun? Oh yeah.
