Re: New PR issue: one or more ultimate receiver?

Jean-Jacques,

Systinet's implementations would not be affected in any way if we made
the change you suggest.

Personally, however, I prefer the current text. I view multicast as an
optimization of sending multiple messages as one up to a branching point
in the message path. This optimization is usable in environments where
it doesn't matter that the message is seen as one and not as many
messages.

I think the 'an ultimate receiver' was meant to indicate that the
message may not actually reach the node, not that there may be multiple
such nodes.

Best regards,
