So what can be done -- is to make some good interface in this
library. It should generic enough for being applied to BSD ip stack
too.
In fact I'm thinking about pfinet reimplementation, but it can be done
after making this library. I forgot to post link to the article, but
probably most of you read it:
http://island.po.cs.msu.su/~nidd/maeda93protocol.pdf
(Original postscript file from ftp.cs.cmu.edu contains picture that
was unparseable by my ghostscript and probably unparseable by yours.)
I ask you to read it and say what you think about it.
It requires inserting some parts of network code into kernel, but it
gives more speed.
Another paper I'll probably look at is
http://citeseer.nj.nec.com/426933.html
It is talking about I/O oriented IPC that i didn't understand still.

native implementation is long term. When I proposed to cut down
currently unused things in this linux code, I thought of it as start
of adopting this code. AFAIR, linux started with BSD tcp/ip
implementation and then evolutioned to current state.
Thanks,
