I have no personal experience with ITF style sparring so I thought I'd ask some questions to any ITFer's out there.

1) Can you make contact the face with a hand technique? Or will you get a point for getting close? Does it have to be open hand?
2) How common is it for someone to score a point from a "perfect" block?
3) Are points electronicly scored at tournaments? (Judges have clickers)

Also, links to ITF sparring videos would be great.
