I have seen bits and pieces that better RDP support is being worked on and I'd like to throw this out for consideration.

My goal would be to pre-deploy the Coder Agent on specific servers that shouldn't behave like disposable workspaces. These may be pre-existing VMs or even physical machines.

The Coder Agent would also allow for users to RDP into them similar to a RDP gateway.
If the user does not have a domain credential linked to the server, a local user would be created, potentially with specific group membership such as Local Administrator.
