[omniORB] A newbie question (well, maybe more than one)

[Eric Damphousse]

Hi Ulf,

Thanks, this is very encouraging indeed. I shall try this right away, 
and see what this does. Experimentation is always a very good way of 
learning, specially, when its just for fun!. I have quite a few machines 
here at home, running diff OSs... this will be fun. Thought I am looking 
at this trough the eyes of a newbie, this object oriented architecture, 
OS independent, blah blah blah is extremely powerful. Cool stuff. Should 
have learned this before!
