The Raspberry Pi board almost fits those specifications as I understand
them (though if "voltage inputs" means A/D converters rather than something
related to Ethernet then those are missing) and is $35 with an Ethernet
port. The board almost fits in an Altoids tin. NetBSD would need to be
ported to it, though I'd like it if someone did that.
