CQC works standalone, at least according to Dean, that he has posted above that he considers it a competitive advantage due to concerns over "stability". Crestron and AMX seem to share that model, and price it accordingly. CQC, being a very small software company, can't price that aggressively for many reasons that also are shared by Cinemar.
MainLobby is highly flexible and can be used both standalone, or integrated with any number of other products including Homeseer, HAL, J River MediaCenter, and lots more. MainLobby integrates with best of breed applications to provide the same Robustnesss that Dean speaks of, but from a different strategy.
I don't think that Dean has been keeping up with MainLobby advances (and I have not CQC advances) as in many posts he speaks of the requirement of MainLobby to be used with another product which, in reality is not the case as MainLobby is robust home automation and media control on it's own merit. MainLobby is a more open application to outside development and integration than most others. This is why it has been succesful in the marketplace as it provides the freedom to explore the advantages of other products both hardware and software to accomplish the end goal.
Dean, as FYI, only a portion of MainLobby customers use another product like Homeseer. They just happen to be the more vocal forum participants as they are really into their hobby, and post on boards like this.
I am not aware that CQC has done any integration with, or other software solutions have tried to integrate with CQC like what is done frequently with MainLobby. Dean has sent me a reply message that it is technically possible, but I didn't get the impression that he found that strategy appealing, so I didn't persue. Always open to that discussion though Dean!
So, CQC so far likes to do it alone, and MainLobby can manage on it's own, or you can addon another software product to really leverage the best in industry approach. For instance, both HAL and Homeseer offer very nice voice recognition. MainLobby could add that feature, but it's really not that attractive from a commercial dealer perspective so the DIY can accomplish this by integration between MainLobby and HS or HAL. So, all of our customers get what they want. This is one example of hundreds.
Another example is one that Dean brings up - DVDProfiler. This is an excellent (best standalone) application to lookup movies. Many folks love this product. Now, if that is your choice, you can manage your coverart and movie metadata there and then easily import into MainLobby's DVDLobby for the best movie presentation and launch control. Now, MainLobby has it's own lookup (that I personally use), but some like DVDProfiler better. So, there is a choice. And, many very cool methods in development that will be the best in industry approaches (tease).
If automation based on Events and Conditionals and Variable changes and Time is what you really want (the essentials to automation), then MainLobby 3 has that all on it's own. Don't forget that MainLobby also is the king of media control as that is it's roots. No one's products compare on this regard IMHO. And, from a music perspective, that comes about by leveraging the best music database and player in the industry - J River Media Center 11. Again, best of breed approach.
One guy can't do it all the best. But, each specialist company can do their part, and MainLobby brings it all together into a highly reliable, hugely configurable, feature rich, supportable product.
