iPIX immersive imaging - patent holders, and evil enforcers, on lots of neat virtual tour and virtual video technologies.
Apple Quicktime VR - info on QTVR and other plugins and 3rd party wares for creating VR tours and such.
IBM HotMedia - IBM's "rich media" offering that works without plugins, all in java. Uniquely, it downloads *only* the java class(es) needed to display the particular type of content being offered. iPIX's 360 suite includes support for HotMedia.
panoguide.com - fantastic resource for panoramic and VR tools that are off the beaten path.
NO IPIX campaign and, uh, Kathy's site - open source developers championing the open VR technology cause. These pages are old but it's good to see a bit of history. iPIX and Apple QTVR work together now so this stuff is most likely moot and for historical purposes only.
The Panorama Factory - shareware tools for producing panoramas and virtual tours.
