Hi Lonnie,

best check ccmake and the repo for existing channels, the documentation
you are using is quite outdated.
As for channels, see the microsoft specifications for RDP.

Specifically for
DRDYNVC: This is kind of a meta channel (there are static and dynamic
channels, the dynamic ones are loaded by this one)
RAIL: Provides the extensions necessary for remote application mode

But if you are creating a server or client these are quite low level and
already implemented in the core library

regards

Armin
