Go ahead...it's pretty easy to re-build the Dachstein kernel if you've got a linux box around, and you can get that second processor running SETI@Home, if nothing else ;-) Note that you won't see much benifit to SMP on a basic LEAF system...linux's network code was extensively re-worked in the 2.4 series kernels to make better use of SMP...AFAIK, adding more CPU's doesn't help 2.2 kernel networking that much, since a lot of the code is tied to one processor... > this is also the machine that I would implement the gigabit > router on, if it turns out feasible, looks like it would save me > about $1000.

Yeah, but you're probably talking about a 4-way machine to handle that kind of work-load ;-) Actually, that's kind of what I'm looking at doing if/when the company I work for craters and I find myslef needing a new job. No, I'm not planning on going into the sprinkler business (although now that you bring it up... :), but essentially building a minimal linux system that's cheap enough to consider it as a replacement for more conventional micro-controller (like you'd find in a sprinkler controller). Using "standard" linux pushes the hardware cost up (requires a 32 bit CPU with MMU, and more RAM and flash than a micro), but you get a lot of "free" features, like ease of development, and instant network connectivity. I figure the hard (parts) cost on a minimal linux system is probably $50-60 right now, kind of depending on how much RAM and Flash you need, vs maybe $20-30 for an embedded micro (less, if you're using an all-in-one device that's not real smart, like for your dishwasher or sprinkler controller...I'm talking about stuff like cold-fire, 68K's, H8's, 80186's & the like). That's a big difference for something that sells for $100-$200, but there's a lot of industrial stuff selling for $500-$1000, where you'd be more able to take the price hit for the additional features...
