Hmm. Wonder where one might go about achieving that?

With only 70% maximum charge, you may need to charge more often (depending on your device), which would shorten the lifespan. There is a tradeoff between too much charge and too many charges. For a given device, you would need to find the "knee of the curve" between mAh/charge and total charges.
I think that the kindle uses so little energy that perhaps charging it to 70% more often may extend the total life, so perhaps your idea is a sound one.
To test it, perhaps you can use the shipping mode script (or diags test) to charge it to 70%. Custom charging firmware could perhaps be based on that script, but perhaps it may be even easier just by programming a /proc or /sys file from a startup script...
