Certainly this is true of the ARM and even the Motorola 68K, as you mention: > For a box that runs mainly as router, apache, postfix, cyrus, ... > even an old MC68k would do just fine (esp. if you are limited > by bandwidth, not CPU cycles...). ...there are a lot of people using an embedded M68K as a low-power applicance computing device. > Perhaps something like Soekris boards could be useful?

I've got a Soekris net4801 sitting right next to me which is running some custom network monitoring/IDS/IPS software, and the Via EPIA mini-ITX form factor is another good choice for low-power computing. The EPIAs seem to have slightly flaky ATA support, though. > Anyone living in a country with exorbitant high taxes on power > lurking here? People here in the US got to pay for Enron and the like, sure, especially those in CA. -- -Chuck
