Hello Joe, etc,
I can answer a few issues on the Vatican contents. They are being delivered and shown using the Zoom technology from iseemedia (www.iseemedia.com). The technology originated from Live Picture Inc, then to be MGI Software, and now iseemedia.
The images are being 'streamed' from an image server, to a java applet client. Different to shoing in say quicktime, or the ptviewer, the image data is being shown on demand in real time, vs the whole image being downloaded all at once. Thus an extrememly large image/panorama can be shown over small bandwidths. This was a pre-requisit for the vatican as they wanted to show high detail, but reach users down to 33k lines in places such as Africa, etc. I am unsure of the resolutions, however from my eye they would be in the range of about 10,000x2000 pixels. The contents in Quicktime would mean several MB to dl.
The contents are not cubicn or spherical. This is in line with their concept of having panoramas to give a general view of the room, and high res 2d images of the art seperately to zoom in on. Even if cubic was there, it would be best as a seperate option, rather than a replacement to the current contents. Also the requirement was high detail being shown in the panoramas. Unless a special system is employed then using wider/fisheye lenses will bring in loss of detail in the distortion.
I'm unsure of the panorama and equipment used. It was not a roundshot though I know that, as Photovista was used to stitch the panoramas together.

And also I would like to know what equipment was used for panorama
shutting
and stitching.
In what resolutin pictures for panoramas where taken.

No, I don't know how they implemented the zooming on the Vatican
Virtual Tours pages. Somebody mentioned maybe they wrote their own
Java viewer applet.
Maybe somebody else on the list has more information, or can figure out
from the web pages?
My guess about equipment would be some kind of Roundshot camera, since
(as Ken Turkowski mentioned in his reply) I can't imagine why they
wouldn't want to have a complete cubic of the Sistine Chapel!
