Hi Dennis,
I am not a expeert in corba but have used it somewhat and try to reply
to ur queries
Corba is quite nice thing u can go for . 
If u need to make connections between two objects(computer etc) again
and again than corba gets heavy as it resolves object  names etc and
can be a bottelneck ..
but in case if u r making connection for  one time and then it is useful.
SSL protection will also increase bottelneck.
If ur making connection again and again thens it better to always go
for simple sockets  , although thre r some issues with them but they r
fast.
Thanks 
Saurabh
