Hi,
I don't see why not, however I'm not clear what the difference would be 
between "native orb actors" and the orbsource actors that Tobin has 
already constructed. Perhaps you can clarify what you mean by native orb 
actors. Tobin has put in the Antelope java interface, which allows the 
standard orb calls of orbopen, orbreap, orbselect, orbreject and a few 
others. Is there anything more direct that you need to do for Kepler 
that isn't already supported by Tobin's actors?

Clarification welcome--
Kent
