Eventially the changes settled down, and for the past few years they

Debian package of ipvsadm actually shipps three different ipvsadm

I wonder if now would be a good time to bite the bullet and design
a new interface that is extendable.

If we really have to break it once for IPv6 anyways, it seems like a
good opportunity. Depends on how invasive the changes would need to
be, of course...

You don't need to break the old interface, just add an additional

You probably already have some ideas on what a better interface would
look like? Especially, how to design it for future backwards
compatibility? And would it still use sockopts or rather one of the
other communication mechanisms?

I'd suggest genetlink or nfnetlink.
