From what I've been able to work through, if you announce the
availability of data on an InfoBus before a DataConsumer joins the
InfoBus, that announcement is lost. But since I'm working on a
multi-frame applet project, I cannot guarantee that all consumers will
join the InfoBus before the producer. (Since all applets will have both
a consumer and a producer, you can never do so.)

I can think of one detection hack -- if the corresponding
dataItemRequested() in the producer does not execute, that means target
consumer never answered. With this, I could set up a flag, launch a
thread to wait 5 seconds and so on.

But obviously, I'd like to implement a more elegant method. Is there
something in the API I'm missing? Has anyone else had to deal with this
issue?
