Michi Henning, another CORBA expert, and co-author of
Advanced CORBA Programming with C++. Not to mention,
Michi's a really nice guy and a great instructor -- I had the
good fortune to have him as an instructor in a CORBA training
class. (Sorry, Michi, but I'm probably still going to use TAO
rather than ORBacus ...)
Steve
Vinoski, the other author of Advanced CORBA ...,
has a slew of Really Useful information on his home page as well.
