I think the 360 degree image things can be a good idea. Though I suppose it depends on what your selling. Its not always appropriate.
What program do you use for that just out of interest? I used a panorama program when I did, I can't remember was it was, but I had to use wide angled lens cameras at certain invertals where it stitched them together and made a .swf file.
Would be very good if you owned a Car garage! Would look impressive on a website
