If you take this idea of communication restrictions to the limit, you could imagine the guessers identifying N sets of cards by a single word each as they discuss their guess. The clue giver listens, then uses the clue that identifies the correct set of N cards.

You really just need an algorithm to generate unique sets of 8 or 9 from the whole board, and identifies those sets by a word.

Yeah it's interesting to take these ideas to the extreme... even at the lower end I don't like it, I think zero communication outside of clues is the best way to follow the spirit of the game. But a little bit of banter and "kibitzing" is what makes it fun too.
