I'm not sure I understand your problem. What's wrong with using TightVNC?

It's normal to use this to send the display from a Pi to another computer so you can control the Pi remotely but I can't see any reason why it wouldn't work the other way round.

The problem would be that Windows doesn't come with a native X-window protocol to send its display to another machine. One has to basically reproduce the Windows "remote access" feature.

oh, you want to capture a PC screen keyboards and use the PI to control it?
two thoughts.
1/. Put windows in a VMware virtual machine and use a web browser
2/. IIRC there are remote video/keyboard hardware solutions designed to remote boot dead windows servers etc. and the like. They sold rather well :-)
E.g.

Thats the cheapest way - a PCI hard that 'intercepts' the screen and keyboards and has what looks like a sperate ethernet port to not interfere with the main IP address on the PC. And the remote machine needs a browser and if I read the sheet right, java.
I wonder if it allows ctrl-alt-del as well. :-)

Ineptocracy
(in-ep-toc?-ra-cy) ? a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.
It sounds to me as though you want a vnc viewer which uses the framebuffer rather than being built on top of X right?
Would directvnc fit the bill?
As for starting it remotely there's something called "listening mode" that some VNC clients have where the connection is initiated from the server end. That's not a facility that directvnc has alas, but you could probably implement similar functionality by having inetd run the appropriate command to connect to the server when it is prodded by the PC.
VNC server on the PC (or rdesktop or what ever - don't do much with windoze) and a VNC viewer on the RPi again don't know what XBMC comes with but if it is linux based (I think it is) then you can install a vnc viewer I'm sure, that way you get to see the PC screen and (if you want/ need) control i as well.
But as I say I may have missed something from this

I think what's confusing everybody (it certainly confused me) is that your original post read as though you were proposing sending video to XBMC as a possible solution to your problem. You didn't say XBMC was a REQUIREMENT. Raspbmc is, as I'm sure you're aware, just a cut-down Debian with XBMC pre-loaded
If you install ManyCam on your Windows system, you can get it to use your windows desktop as the video source for a virtual camera.
You should be able to use that with some webcam broadcasting software ( Not used any myself, but I believe there are a few out there ) to stream the desktop to your xbmc machine.
No idea what resolutions are supported, or if you will get the speed you need, but it's free so give it a go.
