"Standard" is a bit far stretched.  We are talking about a solution that is
shared by BSD and Linux, I think, which are both monolithic Unix like
kernels, and thus have a different understanding about how things should

Of course it could be the same protocol, but it would be silly.  You
would insert a man in the middle which has really nothing to do with this

If I had one you would find it in the savannah task item about it.

That's what I keep saying :)

It needs to be cooperative, but it can be simple.  It also can assume trust
between the communication partners (ie proper behaviour).
