One other model to look at is The Click Modular Router, which is about
modularizing the routing part of the code, as opposed to the end
station code.  Look at http://www.xorp.org because Click, and FreeBSD
are in there.

I have always thought that a network protocol toolkit would be a good
thing, but admit that I have never had time to do the required work on
our stack.  It would take a lot of reworking to get it right, as
others have pointed out already.

But...  If you do it, I want to know about it :-)

Later,
George
