There is a bad link on some pages.  It is a mailman list server with a
private archive, so goto:

 http://gsyc.escet.urjc.es/mailman/private/linux-streams/

and enter your email address and password and you should be redirected
to the list.  (You need cookies enabled.)  This method works for me...

I have assumed maintenance of a GPL'ed release.  The OpenSS7 2.18.1
release builds and load against every current 2.4 and 2.6 kernel and
linux distribution that I could get my hands on.  I will continue to
maintain a GPL'ed release of LiS until our Linux Fast-STREAMS release
will serve as a production replacement.  I would prefer to do active
development only on Linux Fast-STREAMS for obvious reasons.

Do take a look at the list archives for the long-winded discussion on
licensing (GPL vs LGPL)

You can use the OpenSS7 strxns, strinet and strxnet packages to hook
into IP, TCP and UDP using /dev/inet/tcp, /dev/inet/udp and
/dev/inet/rawip in the same fashion as on SVR 4 and Solaris using the
TPI interface or the libxnet (XTI library) from the strxnet package.

It sounds like UDP and RAWIP from the strinet package will meet your
needs.  You can push modules onto /dev/udp or /dev/rawip that use the
TPI interface.  The strinet driver uses a xtios (XTI over sockets)
approach and present a TPI stream that is converted by the driver to and
from a socket internal to the kernel.
