Uhh.. no thanks.  Whatever you do, do *NOT* abuse the mbuf system
for this.  We went to a lot of trouble (well, Garrett specifically)
to rid the stacks of this obscenity.  Do *NOT* generalize it and undo
it.  MT_DUMMYNET must die, not be propagated elsewhere.

If you want to have some general storage mechnaism, do *not* use mbufs
for it.
