Just a suggestion concerning the internal structure of such an adapter:
If you look at Documentation/i2c/smbus-protocol it seems to be better to
implement it only using the SMBus subset of the I2C protocol, if at all

Seems good, the address would be an integer between 0-127 for the standard
7-Bit I2C-addresses? The 10-Bit addresses are included in the I2C standard but
the kernel support is only experimental since no known I2C devic

If you load the i2c_de
Jan,
Do you know how to talk to the i2c via user-space?(Something like libusb or
tty system). Then a non-w1 approach would be easy. There is an example
implementation for the DS2482 in the kernel; module, and the communication
structure is an easy match for OWFS.

I will definately build a board based on the DS2482-800 chip and will test
owfs improvements, too.
Hi,
I'm hoping to have a circuit, and PCB design done over the weekend.
Still waiting on the arrival of a sample chip from Maxim, once I've got
the designs finalised I'll make them available for comment.

Agreed, I just copy-pasted from your post.

Just to avoid confusion
The I2C part is DS2482-x00
x = 1 for 1 port
x = 8 for 8 port

Paul,
This is great
Paul,
This is great news.
I've got samples on the way from maxim of the 2804-x00's so hopefully
will have a prototype interface available for testing soon.
Cheers
