Doable via default IPSEC VPN support in CloudStack.

The default virtual router (VR), already supports IPSEC VPN.

Once you are on the VPN, each host is directly reachable over the private
guest segment. ACLs can then be used on a per host basis to control
network access to RDP ports.

Certainly possible to implement your requirements in ACS.
