Subject Re: Split JavaSpaces and JINI
Date Wed, 10 Dec 2008 12:22:31 GMT
+1  This is not, I would stress, to question or to otherwise lessen  
the value of JINI.  This is just to allow JavaSpaces to live its  
"natural life" and to move what is in JINI but belongs in JavaSpaces  
to JavaSpaces so that a Java implementation of Linda spaces can stand  
on its own.  Then, as Niclas has noted, JINI can use and extend  
JavaSpaces as required.

This seems to me to be a win/win and I believe this would provide  
significant wind to JavaSpaces and JINI sails.
