"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.
