Has this changed recently? I just checked the man pages from a -current
system from early June (the June i386 1.2G snapshot), and it mentions (in
passing) an -ifp and an -ifa option to achieve what everyone's talking
about.

Assuming I understand the subject. :-)

I think the earlier discussion of how the interface command worked was you
gave it the IP address for an interface. If you have multiple interfaces
w/ the same address, you've not achieved your goal of sending the route
via a particular interface.
