It's a quite superficial judgement at this point. Only based on preliminary
examination of the solution. I am not dismissing RDP, it's just not a smooth
line to adoption right now with the difficulties I have had.

... or extensions to the protocol which only freeRDP implement in their
server and client codebase perhaps?

Ha! You are correct. I've been doing this long enough for the rose glasses to
fall off... So quite the opposite, I generally expect that everything that can
snag, will.

In the end though, all I am really paid for is adding remote screen capability
in our product which is quite a subset of a proper generic VNC backend. The
resulting work would not be upstreamable, but would still be of value in the
open source domain for the next party to carry it forward.

Like I said though, I am not there yet. I found it worth a lot of compromise to
comply with standards and existing supported code ;)
