Do you mean STREAMS?, untested STREAMS for Linux (though they're
working w/ QNX) at ftp://ftp.blackdown.org/pub/Linux/LiS
See also the LiS url http://www.gsyc.inf.uc3m.es/~LiS/
BTW, I've also a wish for future Linux systems, a union file system
working fine w/ NFS, any other one out there wanting the same thing?
