I get the feeling you guys are using different definitions of "bus".
I've taken Paul's use of bus to be like a mix bus on an audio mixing console,
which basically means: add all input signals and present the result at the
output. And since we're not talking about analog circuits here, it could be made
to work for *any* number of input signals. I don't know what you mean by
"collisions for more than 2 members".
Could you describe this "crossbar" idea a bit more, or provide a link to more
information? The term is new to me, and I don't understand from your description
how it works or what it's used for.
