I understand and agree with every point you have made. There are two business reasons I see that providing a self-hosted solution would actually be beneficial.

I understand and agree with every point you have made. There are two business reasons I see that providing a self-hosted solution would actually be beneficial. First, it would expand the market potential to include companies that for whatever reason do not want to use the cloud system. Second, it would give another revenue outlet by charging hefty fees for support. How many companies like Apple sell a warranty that the purchaser might not ever use? I could see that happening here too.
