What are you trying to access remotely?? IF the PV has a VNC server, and its enabled, you could use the Google version of VNC viewer to see it. Going through linx with the ETH I/P driver or by manually adding the PV I.P. to the Ethernet Driver, you should be able to see the device online as a node in LINX but you can't actually see the application running.
Perhaps I misunderstand the question!
