[Bertram Ludaescher]

Brandon, Kent, Raja, Frank:

What do you think of creating native orb actors in Kepler? 

There are of course various ways to do indirect orb actors as well:

- through SRB (and SRB actors)
- through web services (and the web service actor
- through ssh (ssh or command line actor)

beforing jumping the gun on this we should think about the pros/cons
of the variants..
