Apple's QUICKTIME does interactive 360 panos, but I've not used it. Here is a pano website [
Panorama Software Panorama Stitcher Panoramic Images. Software VR Photography, QTVR, Quicktime VR ] that might help.
AUTOSTITCH does great panos, but isn't the best for a 360 view. An old tool I use for that is the PHOTOSTITCH program that came with Canon printers. Its 360 mode builds a full-circle image strip with one end copied to the other. Let's say you shot a scene of a mountain sticking above the horizon:
-=-=-M-=-=-=
PHOTOSTICH lets you arrange those frames so the mountain is at one end, then copies it over, giving you a strip like this:
M-=-=-=-=-=-M
The reference point gives the cue that this is a 360 degree view. Unfortunately, PHOTOSTITCH doesn't handle distorted edges nearly as well as does AUTOSTITCH, so such a pano would require a matrix of fairly narrow-FOV images. This might not be the best way to display a property.
AUTOSTITCH and PHOTOSTITCH are the only stichwarez I use so I can't advise on any others, sorry.
