If Bl & Bg had indicators of scope differentiation in the prefix, A could
recognize the difference if it bothered to look. It wouldn't have to, but
if it didn't it would either have to refer the name, or provide C with the
entire list so it could figure out which one works. Brian's C000 thread
was exploring this space.
"Global" addresses can be scoped by administrative/security devices just as
easily as non-globals, so a scope indicator in the address is merely a hint
which may lead the app/stack astray. The only way to determine if a given
address, global or otherwise, will work is to try using it.
SL does not solve -- nor did it create -- this problem any more than RFC1597
did.
