I've done something similar with DC.  I used D/A with a comparator for each
channel.  The D/A output was used to dynamically adjust the trip point.  You
might consider using Hall Effect sensors for current measurement.  For the
environmental monitoring side you might consider the Maxim/Dallas 1-Wire
devices.  You could use either the serial or I2C 1-Wire interface.  

Then again the Maxim/Dallas DS80C4xx series micro was built for applications
like this (aka Dallas TINI).
