Well, don't forget that there still are a few non-Ethernetty networks left. While it would make sense to optimize for Ethernet and its ilk, the generality still needs to be kept around. While this is hardly impossible, I daresay it reduces the motivation to change the current system. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
