Ah, the truth will out!

THE NCS IMPLEMENTATION IS WRITTEN IN PORTABLE C AND HAS BEEN MADE TO
RUN ON MACHINE FROM CRAYS TO PC'S.  I put that in all caps because I
just couldn't bear to have straightjacketed myself to the requirement
of maximum portability and then have people think otherwise.  Just 
want to make it clear.

NIDL supports two input languages:  one that looks like (ANSI) C and
one that looks like Pascal.

The non-Unix parts of DOMAIN/OS are written largely in Pascal.

Small correction:  NCS runs on top of UDP, not TCP.
