A couple of questions
1 - How are you going to handle sleeping nodes, OWFS by its nature polls the
1-wire bus.
2 - You may want to consider sample frequencies, obvious I know the faster you
sample, the shorter the battery life.

I've seen no information that the gpio pins are 5v tolerant in any way.
This is however where the DS2483 comes into it's own over the DS2482. It is
possible to power the 1-wire side from 5v, and the i2c from 3.3v in effect it
has an inbuilt level convertor

The DS2483 is an sot-6 package. There are no SOT pads on the slice of Pi, so
this may make things a little difficult.

Yes but You have to compile osif module and load it and also load i2c-dev
and then it's in /dev/i2c-X
The slower i2c-tiny-usb is already in the kernel and load automatically
but still you have to load i2c-dev.
But i2c-tiny-usb is too slow for DS2482-800
