Can XBMC see HDMI capture card input?

Hi guys,

I plan to get a Roku and add my subscription services to it.
Is there any way I can plug this into the "HDMI in" port on a HDMI capture card installed on my HTPC, and have XBMC display the output as if it were a TV channel?

I understand this would obviously mean I would have to control the Roku box with its own dedicated remote, but I would rather have everything running through the same interface (XBMC).

Is this possible?

Thanks for your advice!
