Multiple ownership is definitely a good idea, especially for those who fail 
to "win" at the end, like me :). However I would probably suggest that the 
owners are listed roughly by the chronological order with respect to how the 
ideas came up (if someone contributes multiple times, choose the events that 
is the most significant). For example, for 1RA it should be something like

Mu-Tsun Tsai ->
Olli Heimo ->
Thierry Le Gleuher ->
Andrew Buchanan

Just a thought. Maybe this is making things too complicated, well, anyway.
