Some would say "build it first let's see".
My reply: how am I sure you will believe when it's built. You may consider it magic or voodoo because it is too advanced for you.
Then build it

A quick Google search shows you're not the first.
But I already see a problem: I'd have to install software, which I don't often do (for security reasons). To take your Telegram example: I only use it in a VM. Bitcointalk (or any other forum for that matter) doesn't require me to install anything.
