It is, in fact, the only interface. As you say, the I/O lines are used
for power (or the power lines are used for I/O, depending how you look
at it). Which I think is really cute. The other highly cute thing is
that you can put any number of iButtons on the same 1-wire interface in
any topology and it still works (I can give a summary of how this works,
if people care).
Note that 1-wire is really 2, of course, but since the other is ground,
you typically don't have to wire it, if you don't want to.
Cheers,
Ben.
