  13. The following question was asked about the Smalltalk Interface 
  14. to Objective-C
  15. >Is communication one-way or two-way?  For example, can a Smalltalk
  16. >method call an Objective-C method which in turn calls a Smalltalk
  17. >method?
  18.  
  19. Yes, two way communication is supported.  Smalltalk already allows
  20. callbacks from Objective-C.  BPG is working to build on that service
  21. to allow event notification where Smalltalk clients will be notified
  22. about significant events in the Objective-C server.
