Actually, #3 should already be that way.  The problem is that a number
of the new protocols (e.g. OLGA) don't work well under memory protection
(so I hear, anyway).  Hence was born #2, which is less powerful than #3
but more flexible.

There are still a number of issues I have to work out, though, before
I'm ready to propose anything solid.  I also have to understand how
the code currently works, especially if I need to make major additions
to it for #2.
