Technically, you can set individual i2c addresses for the ds2482 (3 bits = 8
chips).
http://datasheets.maxim-ic.com/en/ds/DS2482-800-DS2482S-800.pdf
1. I haven't tested this
2. I've read that a bug in the Maxim i2c implementation makes sharing the
i2c line fail in certain circumstances (search their archives).
3. you can specify the i2c address in the linux device name (/dev/i2c-xxx),
but again untested,
4. Why? Each 1-wire line can support hundreds of devices, and you want 40
lines?
5. OWFS doesn't mind lots of 1-wire busses (essentailly unlimited)
6. OWFS shouldn't mind multiple DS2482-800s (though untested).
