The applet example is outdated and not functional anymore, we need
to remove it.

Applets with CORBA are a pain - i would NEVER use CORBA as the protocol
layer. Using a simple socket connection and transport the data XML
formatted is a better approach, probably RMI has some built in support
for typical applet problems.
You will have problems with firewalls and proxies though.
To avoid those problems you can us URLConnection (based on http
like the browser does) but then pushing realtime data back to the applet
is tricky again.

No smart solution is currently available with xmlBlaster.
