Argh, I already have trouble understanding the rationale behind all
the existing closing flows and states :-s Would it be possible to
publish an updated version of the svg ? aj, any chance you could do
the same with your 'flat' version ?

How about the 'commit tx too big' case ? will that just be an error ?

Such a low ceiling bothers me a little bit, because it kind of states
that the micropayment use case is the primary target. Is it ? To me,
scalability and speed are the most interesting properties of
lightning. I would have preferred a higher (1 BTC ?) limit, but I
understand this can be changed. Regarding the risk of bugs, you can't
loose more than the channel capacity so that's another parameter we
can play with I guess.
