Hi Yosi, Given the capability provided by UIMA-1127 to efficiently deal with missing delegates during run time, UIMA AS may be close to providing the functionality you describe below. A new issue, UIMA-1295, has been created to close one required function. Can you review the description in 1295 and comment on what other aspects of peer-to-peer are still missing?
