Sounds good.  Can you post:

1) A description of equipment used (especialy head tracker: how are
   you getting such low delays; and what type of displays are you using)

2) A list of relevant publications (where published, etc).

The research you're doing is just what the VR community needs: some
solid numbers!  Look forward to hearing more from you.
