I think that was what he was sayin'. Then IPv6 is already screwed, isn't it, and a general soloution to the problem for all systems will solve it for FreeBSD at the same time.

IPv6 solves this problem by making my address ranges independent of my ISP/NSP: the address range is sufficiently enlarged, I can get a range assignment of my own. > There is a definite need to be able to flexibly renumber. There's a need for a lot of things which somply aren't being addressed, or less simply, are being purposely ignored. > > de0: DC21040 [10Mb/s] pass 2.3 Ethernet address 00:80:48:e8:1b:b1 > > ----------------------------------------------------***************** > > de0: enabling 10baseT/UTP port > > Of course, when you switch Ethernet cards, you are screwed. So: A) Either: Don't switch ethernet cards B) Or: accept that as part of the overhead associated with switching ethernet cards, and make the decision, when you make it, after taking that fact into account > Although I will tend to think that's a better solution than IP address :-) Bleah.

And even where they don't, you can "spoof" the hardware by trapping the user mode programs access to the kernel mode dongle driver, and lying. So even a hardware soloution -- isn't.
