My question was closed because of "product recommendations". The suggestion is "describe your situation and the specific problem you're trying to solve".
I described my problem I tried to solve, and the only way to solve the problem is to suggest a product. And I had to do it myself, spending very much time. And I've not publicized a single product, I created a list of products that can solve the problem.
I think this is the famous exception that confirm the rule. It's a borderline case, and I ask that the question and answer will be undeleted and reopened, because IMHO they can be very useful to other people with my same problem.
