Yes, and that's the problem with it.

You still need to actually _know_ if the network use WKA or not. Determing
that manually or by probing is not an acceptable solution. If you want WKA
to work automaticly, you would need a way to advertise on the network that
"we use WKA here", like RA. Doing that for all services cause N times amount
of noise which could perhaps be done better dhcp style. It would be better
to use something that could advertise the whole package (ntp, proxy, wins,
bootp, nntp, smtp etc) maybe even depending on who you are (eg mac).
Something like dhcp. Well, at least that's what I think.
