Sharing possible only if applications deterministic
-
applications ARE deterministic or can be made so
|
Copies of applications must be present everywhere
-
but they are, being applets or downloaded via a push channel
|
Environments must be identical
-
Java VM takes care about this
|
Initial state of a newcomer impossible to define
-
not so for good OO design and object serialization mechanism
|
Cannot maintain consistency among copies
-
Difficult ? Impossible. Variety of sync mechanisms available based on JavaBeans/RMI/CORBA etc
|
|
Web model enables event broadcasting!
