Well, here at Unisoft, we port SVR4 and we do POSIX and ABI standards
for it.  I have used and hacked the SVR4 system quite extensively
and I have mixed feelings about it.  I think they have done just
about everything, however I think it may be to much.  It's almost
inconceivable that anyone could ever know all of it.  It's a massive
unwieldy beast.  However, it is nice to have the ability to use
whatever filesystem you like.  Also, it's nice to be able to choose
between sockets and TLI/Streams.  One of the drawbacks though is
a *huge* kernel.  I'ts a real dog on 5 Mg of RAM which makes life
tough for people with PC's or small workstations.  At least it appears
that all the SVR4 people are attempting to conform to the UI/ABI 
POSIX standards so that a consistent interface will be easy to 
find.  

If you have any more specific questions, drop me a line.
