Probably, for the time being, RTCTunnel will not be detected by NWGF as a VPN and therefor could be used to create a VPN that otherwise would be blocked by a FW. If that fails, one could reside to sending jpeg images back-and-forth containing not real pictures but jpeg conform files that consist of encrypted data. I’m not aware that such a JPEGTunnel has ever been written but given the source code of RTCTunnel and the like, it shouldn’t be a very difficult task, eg a nice exercise for a student CS.
