I'm working on the incremental ruleset changing API BTW :)
One of the changes will be that interface matching is not
a default part of every rule, and without wildcards it will
use the ifindex. But since the cost of this feature seems
pretty low, I don't see a compelling reason against it.

Fair enough :)
