Never mind about the camera, any brand or medium (Including compact digital cameras) will do these tricks.
The choice for the lens for this kind of assignment is a bit tricky.

First, why a 20mm ?

The answer is: Firstly, we have to admit - we are lazy and besides, to capture more of the studio surrounding, the Nikkor 20mm's 92 degrees viewpoint seems perfect for this particular interior job. All we need is 18 slight overlapping shots (only for 20mm and the Kardan tripod head is very helpful) for us to do the stiching work with the Apple's pananoma stiching software later.

The previous QTVR assignment we did was for the International Award Winning Website on
World Youth Soccer Championship '97 that held in Malaysia (it generated more than 4 million hits in 3 1/2 week). All the six venues (the Stadiums) were supplemented with a QTVR scenario - the only difference is - we were using a digital video to do the captures and convert them into individual Photoshop files and edit later into QTVR formats and ten of thousand visitors downloaded the QTVR scenes.

There are more sample works of QTVR we created for my clients..

For a preview of how individual images (prints) have been digitized for stiching work later with the Apple's QTVR software.

Basically, we are digitising a conventional medium into a new medium. I felt conventional 35mm is much easier to handle than digital video for interior works - especially to retain the ambience and the atmosphere of the interior. The warm color temperature is well duplicated through shortcoming of the film - that's what we accept naturally warmth orange tone for photographs of interior. In fact, the original prints were too excessive and we need to tone down the tint to lower level.

Well, most digital video camera doesn't have wideangled zoom lens (I think Canon's L-1 does provide a interchangeable mount for their EF lenses to be used for the L-1. Thus, that's why we selected a 20mm manual lens for this purpose. When selecting zoom lens as your source, you have to calculate the relative number of overlapping scenes with the angle of view and you have to make sure the zoom doesn't move which later you will have tons of problem during stiching with the change of perspective.

For Internet broadcasting: the quality of the images can be quite forgiving. Essentially this is a compromise for the speed of downloading, more convenient is the new Portable Digital Camera models, it should able to yield pretty good results for this kind of application.
