We're looking at buying some additional hardware, but would like to get
some reviews / opinions of these products before diving into the tar
pit they call procurement around here. ( 0.1 smileys here)

1. New Goggles - the Cyberface 2 from LEEP Optics appears to have it
all over the VPL HRX - wider field of view, comparable pixels/degree,
greater apparent resolution 1481 H by 84 V (although I don't think I
completely understand how they derive these "equivalent linear
resolution" numbers), both RGB and NTSC input, and a SUBSTANTIALLY
lower price ($8K vs $50K).  Can anyone that has a pair of these comment
on how they like them and how they stack up against the HRXs (or anything 
else available)?

2. A Big Bird (from Ascension Technologies) with at least 8 sensors.
They claim to provide position tracking in a hemisphere with an 8 foot
radius.  It's still tethered, so it's not a long-term solution.

3. A tactile feedback setup from Xtensory - some tactors mounted on the
fingertips, others mounted elsewhere on the arms.

When you swim up a creek, and an eel bites your cheek, that's a moray!
