It's also possible to just use python/perl for mixing. Ie. for each song
you record and mix, write a dedicated python/perl script. It's quite easy
to add a small loop that executes ECI commands based on current
engine-position (--> automation).
And once you've written done the above once, you can use the script as a
template for future mixes.

That's quite a difficult problem as you need to maintain max-peak-value
for the whole track. And this again requires multiphase operation (like
ecanormalize has two phases: -ev + -ea).
