with the old APPLET tag there was name=. I think it has disappeared in
HTML5 OBJECT. Logically ID= should work, but I don't think there is a
method to read it.

In my case, I generate the OBJECT tags with a macro generator, so it
is no problem to add a sequence number on page parameter to uniquely
identify applets.

<param name="instance" value="12">

I suspect that using static for communication will have the same
problem.  If the browser starts putting your Applets in different
JVMs, they will each get their own static area.
