The key trick is the fact seperation. The information is in the public domain. So, you have to be a "reporter" rather than a "republisher" if that makes sense. The raw data may or may not be subject to certain considerations, the the only really valuable part -- the fact/information -- is more or less urestricted.

The question is, will CL now take steps to make the data more "private" (eg, member only, even if free...etc) or will they take steps to re-introduce themselves into a critical step of actionable use (must login for contact details, etc). CL could start to look like an apartment broker, though, if they follow through with this latter approach.

So this is an interesting dynamic to watch how it plays out. It might aso still be interesting to use a-padmapper-like-service, even as a complement to CL service. If I just had to get 1-5 things its no problem. But sorting 200-400? to find 5 is a PITA, because wading CL is increasingly inneficient. Its a discovery issue.
