I've never come across a plugin that does what you want. However, RDP is 
an open protocol and there are opensource clients for it, implementing 
the protocol.

RDP works by sending images followed by deltas against the first image, 
along with some pointers on "here's your cursor" and things like that. 
Deciding if it's the login screen or not would require fetching an image 
over the network and passing it to image-recognition software. It's not 
extremely complicated, but still far from easy.
