Ok, If I understood it right, there are two problems:
1- Instead of using the IP address of a local interface to refer to it, use
some other scheme that really ensures it is unique, for example
IP/interface_name. BUT, what about HELLOs received from other nodes?... we
cannot know the interface name through which they went out.
2- Some OSes do not allow binding a socket to a specific interface.
Regarding (1), the problem seems to be using a unique identifier to refer to
links when remote interface IP is no longer unique. What about using IP plus
the interface through it was received ?:
I think this would work and would allow clean interface and link management.
Of course, I know next to nothing about olsrd internals, so, please feel
free to correct me.
Regarding (2), Andreas meant that whatever the workaround to SO_BINDTODEVICE
that is being used in the BSD port, will not work in this situation. Well,
so be it. If someone is in such a special case as you and me are, he might
as well switch to othe OS.

Can you please explain why is your patch "non RFC-compliant" ?
