This post may be of special interest David... it looks like there could be a way to download point clouds from PhotoSynth and use them for photogrammetry... or at least this link suggests as much.
See if you can dig deeper on this and learn more?

(Some of these require fancy hardware and graphics cards... Susa's office computer may be able to handle these though, if the lab computer can't)
Also, has anyone given 123D Catch a serious try?
