Hi Roy,

Good to hear from you.

The Paho client came directly from mosquitto.py, so there are really
minimal differences. I have been doing development on the mosquitto
side and then porting to Paho, but now that mosquitto is in the
process of moving to eclipse, Paho will ultimately become the
supported option. I'm going to do everything I can to try and make
sure that it's a straightforward change for people.

I'd be very interested to hear if you don't see the broken pipe
problem in the Paho client because it would mean that some buggy
changes have been introduced to mosquitto.py. I'm assuming that you
were using an up to date version of course.

Cheers,

Roger
