I might be beating a dead horse here but I’m still a bit confused. Based on the comments of my last post on this subject here’s what I understand to be true.

Trulia must get permission from brokers and MLS providers for a free app that provides leads to agents.

Zillow doesn’t need to get permission to power a free app, Google Now, using ListHub data. They can just zip up a data file and send it directly to Google, no permission required, no questions asked.

What am I missing here?
