Well, it works.  Its image quality is comparable to the IndyCam, though;
that is to say it sucks.

Yeah, there are a few applications that use the IndyCam or MooseCam as a
web cam.

Sure.  You'll need the A/V module to plug it in, though.

Nothing.  The R10K generates too much heat to use two disks in the O2,
and, rather than redesign the cooling system for the R10k and R12k
systems, SGI just blocked off the second SCA port.

The difference is staggering.  The R10k O2, clock-for-clock, is slower
than an Indigo2 R10k (for most things--the O2 is faster at 2D graphics
becuase GIO64 is just barely fast enough for Impact), and Octane will
slay both of them.  The Octane has phenomenal I/O bandwidth and memory
bandwidth.  The O2 just can't keep the R10k fed.

There are some things the O2 does better.  Anything involving textures
or analog/digital video is faster on the O2 than on the Octane without a
hefty upgrade to the Octane.  However, in terms of computational power
or 3D geometry, the Octane is a hands-down winner.
