Are there RDP server apps on mobile platforms (iOS and Android) that take advantage of Windows' native RDP, Instead of their own solutions?   I would think the answer should be positive if the performance advantage is there and there is no need to develop its own protocol.  (Though I don't know whether they need to pay license to MS)
I just noticed Windows 8 let you setup remote access w/ an email (I don't remember seeing it in Win 7).  I wonder if configuring RDP on Windows 8 is significantly easier than on previous Windows.
