Can one do rd in rinda, too?  I have looked into TupleSpaceProxy but
it only provides in and out.

I'm thinking of the case where a client object logs in and other
clients must be notified.  They want the tuple with that information
but must not take it away from the space.

By the way, in a normal situation I would implement notifications via
events and callbacks.  Is a-thread-for-each-event listening for a
tuple pattern the preferred way to do it in TupleSpace?

Now *that* is what I call an understatement. :-)
