This is a really dangerous project. Use at your own risk.
By directly ethernet without magnetics to an AVR, you may cause serious damage, fire, or anything else crazy if there is a DC offset. It does not follow 802.3 standards for 10Base-T Ethernet
It has two projects in it: t85: uses differential signaling with fixed packets, similar to another person's project, igorplug, found here: http://www.cesko.host.sk/IgorPlugUSB/IgorPlug-USB%20%28AVR%29_eng.htm
t85spi: uses the USI, and can send/receive arbitrary packets.
Schematics are in the "hardware/" folder.
See the youtube video for more info:

Paper on T85spi is found in the "paper/" folder.
