omniORB doesn't currently support the portable interceptors (but it has 
it's own set of interceptors -- that are not fine-grained enough as far 
as I can tell: they do not support per-object interception, see: 
http://omniorb.sourceforge.net/omni41/omniORB/omniORB010.html ).

 From skimming the Portable Interceptors specs (in 2.6 and 3.1) it seems 
those would help as those can be set per object - am I right?
