This is really interesting, a german company made a network enabled linux system in an RJ-45 jack. It’s called “Picotux”. It has a 2.4.27 uClinux port. There is also an 802.11b enabled version of it (the antenna is bigger than the machine!!). I really like this kind of small devices, perhaps I can put one on the fridge and have a web server on the refrigerator!
