Is what I was responding to. Wasn't criticizing the posted product implementation choices or demanding a rewrite. I see how it could be read that way, which is unfortunate.

Parent comment asked a number of questions that all suggested a server was a requirement. If scale becomes any issue for a service like this, there are approaches other than shutting down the service due to server / maintenance costs.
