[Rq-rules] Knockback domino

[perala at cc.joensuu.fi]

I had another moment of Munchkinism. Here is the question: Can knockback into
people cause a chain reaction?

For instance, lets say that a Giant (STR 170, SIZ 170) is cranky and punches
person A (SIZ 12) in face. He recieves 72 (d3+20d6) points of damage and flies
into person B (SIZ 11). Flight is 60 meters and according to Knockback into
people-rule both recieve d6 points of damage per 5 meters or fractions flown.
That means 12d6 points of damage, on average 42 points. Now, does it end here,
or does person B also take flight for the damage he got into person C (SIZ 14)?
That would mean 6d6, or 21 points of damage to C and 7 meters of flight into D
(SIZ 18), who gets 2d6 damage and no further knockback. For the sake of
argument lets assume all of Giant, A, B, C and D are correctly positioned for
this effect to be possible.

I'm for domino - effect, since I found no rule to forbid it, but I might be
missing something essential. Comments?

Furthermore if domino - effect was possible, could it be done on purpose with
aiming and all (like in biljard)? And if it could be done, what would it take
(an aimed blow perhaps)?
