"Is it possible to ____?" is generally considered too broad to be a good question for Stack Overflow—the answer is usually: "yes, it's probably possible, but describing how to do it would entail designing a large piece of software." Instead, you should try to build it, and ask a question when you encounter a specific problem. Please see Why is “Is it possible to…” a poorly worded question? for more information. — Ryan M 44 secs ago

Too many questions in a single post. Pls focus on one question, not on your entire design. Alternatively, you can move the question to software engineering sister site of SO, which offers assistance in high level design questions. — Shadow 15 secs ago
