Marks are preserved, so that works, but I agree that having seperate
interfaces is much more managable.

2.6 has become mainstream on full blown PC's. You cannot run a distro on a
pentium-4 machine with 2.4 and expect your hardware to work. For embedded
devices, they are still very much as 2.4 though on the move. But the lack of
a "stable" 2.6 kernel is keeping back a lot of people on 2.4 there.

I'd love to see the features of the stack merge together, though there is no
harm in having choice. It is very unfortunate though that we have no nat-t
support as a netfilter module, so that KLIPS requires a total kernel recompile
at this point. (If anyone wishes to donate resources to this effort, contact
me offlist)
