OK, first time out with the new rig, consisting of:
Flip Ultra HD
Ikelite housing + 67mm port adapter
Inon UWL-100 type 2 wide angle wet lens
All footage shot at about 20-30fsw, available light.
I wasn't the cameraman this round, so I can't really say anything yet about how the housing/camera performed, but the instructor, who was shooting the camera, mentioned that it did feel slightly negative in the water with the WA lens attached (the lens itself is about 1lb negative in the water).
Overall impressions are positive, and the only big ding on the system so far is that the Flip's lens is so telephoto that you practically *need* a ~$300 wide angle lens in order to get slightly better what you would get out of a digicam with a 28mm native lens. In my informal tests, the Flip + wide lens nets you about 24mm coverage.
