[Donal Lafferty] 
ATM there is code for an RDP console proxy at

This source is assigned to ASF; however, there remain two problems.

First, RDP support may not be complete.  AFAIK, Hyper-V exposes the virtual frame buffer of
each VM through a single RDP server on port 2179.  The "Session Selection Extension" is used
to select which VM console to transmit to a connection [1][2][3].  I'm not sure that this
package includes the necessary extension.

Second, I've not attempted to add a package created from this source to the system VM, and
I'm not clear how the management console would start it.

for a discussion of its implementation
[2] for the technical specification
of RDP's "Session Selection Extension" (aka MSRDP-EPS)
[3] for discussion indicating FreeRDP have an
example of the necessary message exchange.
