i have suggested something in the first mail.  have you read it?

while i tend to agree that the provider/consumer model is a bit more
complicated than necessary here, i don't think that limiting providers to
ac adapters and batteries simplifies things a lot.  what i suggested
is a middle of them.  ie. while allowing to have various providers which
is not either ac adapters or batteries, consider the whole system as
a single consumer.
