I to also recently discovered Icarus. There was a script for importing camera data into blender, but I have never really used that program.

I think you had to export the data as a text file (human readable file?). Unfortunately I don't know if this format can be converted to a poser camera file or not. After giving us better lighting etc to match objects up with their backgrounds, I would hope that the next edition of Poser would include more support for matching movement with background footage, even if it was an extra that you had to pay for.
