No.
Stuart, what's your motivation for thinking so? -
NetMap is a zero-copying high-performance ethernet frame IO API that
works via select() and ioctl on an FD and a linked list of memory
buffers.
Perhaps there are some X11-style weaknesses in the security model,
but,
at least as an optional feature in an OS, what do you see that is not
perfect or reasonable about it (in particular in OpenBSD's current
absence of someting to fill the same function)?
It has already been discussed before on this mailing-list. Please read
the archives.

I saw those posts back then but did not feel so convinced 'against'
(though I agree TCP stack reimplementation in userland would be useless)
-
What about the usecases software-implemented networking switch or
networking bridge, with or without filtering or transformation features?
And what about the usecase of using the ethernet cable as a high-speed
serial cable?
