Hi,

These reports are related to the post 1.01 development version.

Yes it is. But the reason is, that wires do not transfer move operations 
from one stone to the other, but stone push impulses instead. We are 
thus speaking of push-wires. A boulder moving by itself causes no push 
impulses to be transfered to its fellows. But if you move the boulder by 
a pulsing stoneimpulse the wired fellows will receive the impulse and 
move accordingly.

Raoul explanation answers the question why impulses are just send to 
direct connected stones and not forwarded to all stones in a wired stone 
collection. This is indeed a matter of providing the most interesting 
behaviour. Andreas and Raoul did approach the resulting feature with a 
mathematical theory - at least for independent stones not being blocked 
by others they came up with an interesting theory :-)

It is feasible to code and I think it is a valuable additional 
application pattern for pipes and the mail stone. I guess we should add 
this feature to the key, the coin and the floppy item.
