Incremental uploads: Publish first, upload later

It would be nice if the Photosynth uploader first published the synth, then uploaded low resolution versions of the most important images, then finally added the high resolution images in order of importance.

Importance could be estimated by relative surface area and difference of viewpoint, so that the high resolution shots of similar viewpoints and zoomed in shots of finer details are uploaded last of all.

This would give a better user experience; cutting down on waiting time, knowing how 'synthy' the scene is before the upload completes, and having the ability to cancel a bad synth before it's finished. It would give a much better impression of the technology to impatient users with modern PCs and "high speed" internet connections but actually have rather low upload bandwidth.
