Has Anyone tried implementing I2C over long distances and if so how can it be done and what distances are achievable ?

I have used a pair of Philips P82B715 which was specifically designed for I2C devices.

I haven't used it in an I2C application, but have used it with the Dallas 1-W family and can reliably communicate over 2000 feet.

I have gone to 20+ meters using telephone cable (2 twisted pairs) but I do
not like the S/N ratio in an office environment and the ground current
problems. I used a bit banged master (PIC) which was slow and did check
each bit twice to hunt for noise (kind of) on receive. For this kind of
distance RS232 at 256 kBps is probably better.

       I have no idea how out of spec I am, but I have an I2C network with the
farthest device being about 20 meters. It seems to work OK. TTYL
