And the first one - or did CORBA get a discovery mechanism since I last

Last I heard, CORBA needed some external (non-CORBA, non-standard)
bootstrap for its discovery, which was highly implementation dependent
and therefore not interoperable. Most textbook examples seemed to skip
over the problem by asking the user to copy a 2-3 line base-64(?) stream
to the other program, taking care to avoid line-break problems, at which
point it's not surprising that most people would throw the book across
the room and use something else (ie whatever mechanism they would've had
to use to do the bootstrap).
