The problem is that source-specific routing never worked right in
Linux since they added the CONFIG_IPV6_SUBTREES option. And before
this point it did not worked at all.
The question about "existing users" is a little bit crazy because how
can there be an existing user if no working implementation exists.
I agree that SmartGateway without tunnel and MPTCP are two very useful
candidates for the kernel option.
Building an option into OLSRv2 to allow source-specific default routes
should not be difficult, we just have to make sure that we handle the
case well if there are routers in the network without the capability
of source-specific routing.
