I'm not knowledgeable about RDP stuff code-wise, but I would really appreciate 
a more up-to-date README.

Like: Is it supposed to still be an example server (then why does it have a 
KCM?) An explanation of why a user would care would be appreciated, is this 
the "RDP" for wayland we need? It already has a good start with the supported/
unsupported client list and the command line options, just needs a bit more. 
If you update the tagline don't forget to change the repo description as well.
