Tandem Backgammon

If you play chess you might have heard of (and played) a very fun variant
called Bughouse Chess (also known as Tandem Chess) which is played between
two 2-players teams.

"Tandem Backgammon" was Fabrice Liardet's attempt to create something
similar for backgammon.  I really like the idea and would like to try out
this variant as soon as I get a chance. So I was wondering if anyone here
has played it and/or has an opinion about it?  Here are the rules and you
can read more here:

Rules of Tandem Backgammon

Main rules

1. Two two-players teams (team A, players A1 and A2, team B, players B1 and
   B2) play a match to n points on two independent backgammon boards (A1 vs
   B1, A2 vs B2), each with its own cube and its own clock. Each pair of
   games is played simultaneously : the clocks are started in the same
   time. After one of the games is finished, the other one is played until
   the end.

2. All games count towards the same scoreline. E.g. if in the first pair of
   games A1 wins a doubled gammon and A2 loses a single game, team A will
   lead 4-1.

3. The clocks are reset after each pair of games. The recommended time
   control is 2 minutes per game plus the usual 12-15 seconds of increment.


4. If a team reaches n points by winning the first of the two simultaneous
   games, the other game is still played until the end. If both teams reach
   n points in the same pair of games, the match is a draw.

Variant 4'. If the tournament format requires a winner, then as soon as one
   team reaches n points the match is over, even if the second game is
   still unfinished.

5. If a player forfeits on time, his opponent scores the maximum number of
   points which is still possible in the game (generally, three times the
   cube value).

Fuzzy variant 5'. if the players agree that the forfeiting player can avoid
   a gammon or a backgammon by minimally competent play, that player
   doesn't lose the points of a single game, or respectively of a gammon.

6. ("Crawford" rule) When the opponents are 1 or 2 points away from winning
   the match at the start of the game, it is allowed to send the cube in
   only one of the two simultaneous games. That cube can very well be a
   redouble to 4. The above rule applies to all games played from those
   scores : there is no post-Crawford.

7. Unrestricted communication is allowed within a team, but not manual
   intereference on the partner's board.
