I have failed so far to get the Checkpoint VPN solution working either on my Surface RT... there the amount of settings available in the new Metro VPN UI is pretty limited, and there is little-to-no documentation (understandable... for a little while?) about how to set it up properly.
I assume it "works", but the setup is just not clear yet.
There is a "CheckPointVpnPluginApp.exe" in C:\Windows\vpnplugins, but it won't run from the desktop (requires an appcontainer that isn't available yet? odd?)
Windows RT in the workplace requires VPN as the "killer app" to be viable, in my opinion. I hope Microsoft is listening and invests properly in getting as many VPN vendors up-and-running by the time 8.1 ships.
