This is *not* a good reason (100 million users use MS Windows, if
it's good enough for them, it's good enough for me...). Just remember
that that DCE/RPC is *not* a well designed RPC system. Study the
ONC code for a *simple*, *efficient*, easy to port RPC system. It
wasn't adopted due to political reasons (being designed by Sun)
but is *far* superior to DCE. ONC-RPC is used in thousands more
projects than DCE and has been ported to platforms such as DOS
and Novell for heavens sake. Think about the reasons for that.

If you don't know the ONC RPC code then I suggest you study
it. You won't want to go back to DCE.

The directory structure in Samba is pretty clear about
which bits go where these days. If you want to work on
the DCE-RPC code you know where to find it :-).

Indeed. Why do you think no-one with any sense uses DCE.
Samba needs it to be compatible with NT - but "thus far
and no further".
