I was just looking at the pyorbit web site, and thought it would probably be a good idea to put a link to the CORBA 2.3 specification up there. It is available in postscript and pdf form at: http://www.omg.org/corba/corbaiiop.html It has good descriptions of the CORBA services and the C language mapping among other things. It seems to be written well and describes how a lot of the things we probably want to use in pyorbit work. James. -- Email: james at daa.com.au WWW: http://www.daa.com.au/~james/
