C# remote access app

RDP

I want to make an app similar to teamviewer but my own. I have a few questions.

So far I have:
1) My desktop captured and displayed fine.
2) I have a socket server accepting clients asynchronous and accepting commands and sending them back.

My Questions:
1) If my client sends the RDP stream to the server, how do I store this stream?
2) What’s the best way to store the connected client info? Keep it in a class? Or write it to a db?
3) How do I store the data stream?
4) If a client connects how do I pull that stream?

Thank You in advanced!
