hmm, would that allow sibling namespaces to connect to each other ? If so, 
I'm not in favor of such a solution. 

I understand the need. we had a similar issue with the command line tool 
pgsl. Could we work something out with the capabilities ? or make an 
exception if your ->nsproxy->net_ns == init_net ? 

Thanks,
