named pipes and unix sockets

[Jerome Freedman]

for an application. The FM is really uninformative about
named pipes by the way as were most of the other "standard
references". I found useable/understandable examples in
"Unix Network Programming" although even these were rather
spare. So my questions:

   1) Is there anything out there in public domain that
actually uses named pipes?

   2) If not (and I almost would bet on this) why are they
there?

   3) What about Unix domain sockets vs named pipes? They 
look about the same except that they look different ;)
