If there is someone out there who actually understands how SMBus works
in an real system, could you please email me? Or if you know someone who
knows, could you have them email me?

We're trying to hunt down these questions:

- You have a smart battery and smart battery charger on the same SMBus.
But something has to tell the smart battery charger to actually start
charging? If so, who does this? Who asks the battery about its charge
rate and capacity, checks that there's sufficient shore power, and then
turns on battery charging? Is this the "embedded controller"?

- Assuming it's the "embedded controller" that does this coordination,
especially when the host is off, are there generic controllers out
there? Or does everyone just throw a microcontroller at this?
