One part of your question i can answer :
The presentation of a VmWare Horizon client can be over RDP, PCoIP
The fact that local shared resources are shown as "\\tsclient\Bla" indicates that its RDP presented through the VmWare Agent/Client
Since that stack (TCP 3389) is already taken by the RDP protocol i would reckon that starting another service on that port would only be possible if you would recompile the RDP Client and install that in the golden image on the VmWare View environment. (reverting to the snapshot would remove your alterations).
