As mentioned in another question, I've been unable to connect through the Remote Desktop metro app to some computers, in particular those requiring VPN access or load balancers.

I'm considering purchasing a Microsoft Surface RT, but given that the app store hasn't matured significantly yet and some niche software will likely never be ported to the Modern UI, I must have acess to remote systems somehow. Until Citrix fixes the receiver app for Windows 8, I'm stuck using remote desktop. Which doesn't work.
