Line Drivers for 1-Wire bus

We have had several discussions about folks having problems driving long 1-wire buses or
noisy environments. While I have not had a problem with my designs thought this Ideas
for Design in the April 2015 print Electronics Design Magazine might be helpful.

It uses half of a NXP PCA9600 I2C buffer at each end of the cable. The buffer separates
the bidirectional 1-wire data into TX and Rx directions. According to the article it is
transparent, so no software changes required.

before inserting electronics which could fail some topological criteria should be fulfilled:

I acknoledge that the topology is bad, if one sensor may ruin the whole bus...
Here we need a successor to 1-wire. Dow you know about alternatives like?

Tom,
 
That is a smart way to use PCA9600 chip.  A good electronics engineer would appreciate this kind of spark of mind.
In 2.2.2 hardware and later firmware releases, it addressed longer 1-wire bus issue. However, if environment noise is too much, this method would provide better handling to that situation.
 
Thanks for bring this kind of idea to the forum.
